Look up the token, find its white paper, and read through it. You should do this for any cryptocurrency to determine if there's long-term potential for it to increase in value. Check the pattern on trading volume. If it's spiked recently and volume appears to be trending higher, be cautious. US News. Photo by Tima Miroshnichenko from Pexels.
It mostly happens when there's not plenty of information to crypto buyers. How to Avoid Crypto Scams? They estimate that the ban increased token prices by about This figure displays volumes Panel A and prices Panel B of Bittrex cryptocurrencies and the control cryptocurrencies. The treatment group comprises cryptocurrencies listed on Bittrex on November 24, , and the control group includes the matched cryptocurrencies not listed on Bittrex at that time.
The control sample is formed by matching each coin token listed on Bittrex to a non-Bittrex coin token with the closest propensity score, where the propensity score is estimated using trading volume over the period running from 60 days to 31 days before the ban, market capitalization 31 days before the ban, cryptocurrency age, and past five-day return — the return during the five-day period before a pump event. The x-axis is the day relative to November 24, Volume is measured as the natural logarithm of the ratio between volume on day t and the average volume over the period from 60 days to 31 days before the ban.
Price is defined as the natural logarithm of the ratio between the end-of-day price and the price at the end of day Each point on the solid lines is the average across either the Bittrex cryptocurrencies or other control cryptocurrencies.

On traditional exchanges, this practice is illegal and is strictly governed. However, due to the lack of cryptocurrency trading regulations in many countries, cryptomarket players are forced to develop countermeasures on their own. Pump is the market situation that leads to very fast and fundamentally unreasonable growth of a cryptocurrency rate.
This usually arises from the deliberate actions of experienced traders. Most often, a successful pump is followed by a price rollback or a so-called dump. Dump from English to dump or to drop is the market situation completely opposite to the pump. A dump is an intentional disposition of assets in huge quantities, aimed at artificial rate lowering in the short term.
The dump which is next to the pump allows manipulators to earn money from gullible traders who bought coins at an artificially high cost. A pump-and-dump scheme has been around for a long time. If not, then, first of all, you should know about the main players participating in this con: traders-promoters and traders-investors. The first ones are well aware of the upcoming manipulation scheme, and their main goal is to attract the second ones to the game. And, by the way, if in poker those who can easily bring you a profit are called fish compared to fish caught on a hook , then, in the world of digital money, flunky traders are called hamsters which are not the smartest animals, you must agree.
Large-scale pumps cannot start just like that because almost always these are well-thought-out and coordinated actions of several tens, hundreds people. They need a lot of money for big pumps, especially if they are going to raise any more or less well-known currency. Here are some signs of a pumped currency that will allow you not to be trapped with your investments:.
Having traced these signals, an experienced trader can predict a pumping and have time to enter it with the start of the first wave when pumpers or pumping groups begin to buy up cryptocurrency en masse. For this, we would have to constantly monitor market schedules of many cryptocurrencies.
But there are alternatives:. Short-term — the value of a currency is raised to unprecedented heights in a matter of seconds. This type of pumping requires a large number of traders. Usually, a timer is set for a time when the trading pair will be announced on which cryptocurrency will be bought. As soon as the time comes to an end, the name of the currency you want to buy is laid out on a public channel. Example of a pumping timer. Long-term is a pump that lasts from several minutes to several days.
Currencies and terms are announced in advance. As a rule, there are chosen really promising coins. All participants also get various news on the selected currency, which they publish on social networks, chats, exchanges, and other places where people are interested in it. At the same time, there is a gradual process of purchasing the declared currency. All pump participants — promoters — have to start buying the agreed cryptocurrency at the appointed time, thereby raising its quotes.
This is the first wave of the pump. Promoters can use reliable information to argue a reason for the growth of the cryptocurrency rate. For example, you may receive information that the developers have updated the site. However, it can be completely fabricated. In the context of this paper, unsupervised anomaly detection will be the focus, as no labelled training data is currently available for cryptocurrency pump-and-dump schemes see Discussion.
Conditional anomalies consider contextual information about the setting Song et al. This is described through indicator variables , of which the values may be directly indicative of an anomaly, and environment variables , whose variables are not directly indicative of an anomaly.
The indicator variables are determined to be anomalous depending on the values of the environmental variables. In the current context this means the goal is to locate the breakout indicators, with respect to the reinforcers Table 2. For the scope of this paper, we do not consider the reinforcer of whether a symbol pair was present on multiple exchanges, due to the amount of data available.
Thus, the goal is to locate corresponding price and volume spikes of coins with a low market cap that are trading for other cryptocurrencies. The anomaly detection technique utilised is a thresholding technique, inspired by previous research regarding denial of service attacks on a network Siris and Papagalou For a particular value, a simple moving average is computed by taking the average of previous values in a given time window, the length which is known as the lag factor.
In this way, one can compare a value to the trend over a time period, as opposed to a singular value, allowing for the detection of local anomalies in comparison to recent history. This type of thresholding algorithm, allows us to provide a functioning baseline which further research could then expand upon with more sophisticated algorithms. Additionally, as more is learned about cryptocurrency pump-and-dump schemes, it is likely that more domain information e.
If the high price at any given point is greater than the computed anomaly threshold for that point, then the point is determined to be anomalous. An instance x is a particular observation in the time series that is associated with the respective OHLCV values. The goal is to detect local conditional point anomalies, that is the co-occurrence of both a price anomaly and a volume anomaly.
There are perhaps other contextual indicators that could be investigated, though for the scope of this paper, only the two mentioned above will be looked at. The market cap of a coin is defined as its price times the supply, and represents a way of judging the popularity, or size, of a coin. The top ten coins from the dataset and the percent of the total market cap they account for are shown in Table 4. This section investigates various values for the different parameters and shows how changing these affects the results found, with the goal of providing a suggestion for balanced parameters.
Hopefully, these parameters could then be taken to a real-time system, to be further monitored and tuned as time progresses. It is possible to formulate expectations based on the domain information presented in earlier sections. Additionally, since this paper only simulates real-time detection, it is possible to look forward in time, and see which of the alleged pumps were followed by a marked drop in price, which could be an indication of users dumping their coins, making it more likely that the preceding pump was the result of nefarious activity i.
While these may be interesting points to investigate, making the parameters stricter could help reduce false positives i. Ultimately the goal is to find a set of balanced parameters that filter the points detected down to a more reasonable number that can then be further assessed by humans. Figure 4 shows an example of an annotated candlestick chart using the initial parameters. We increased the estimation window to 24 h, so it required a more drastic change in comparison to the average.
This led to detecting alleged pump-and-dumps over 20 days, about 0. With the information gained from the previous two parameter sets, we attempted to find a balance between the two. This resulted in about 1. An illustration of how the percentage of symbols analysed relates to the percentage of pumps detected is shown in Fig.
Breaking down the pump-and-dumps on a symbol level allows for a look into which cryptocurrencies, are disproportionately often affected, and hence more vulnerable Table 6. This is consistent with the notion that specific coins may be targeted more often than others. Also interesting to note is that five of the top ten most pumped coins were pumped on the Bittrex exchange. Further research could perhaps investigate the properties of these coins, in an attempt to see if there are links between the most pumped coins.
The individual spikes have been muted in the figure, to highlight only the pump-and-dumps. The resulting graph depicts rather suspicious trading activity, with many periods of lower price and volume, followed by significant spikes in both. During the 9-day period shown eight pumps were detected. Regardless of whether it is directly the result of nefarious activity, it is still a pattern which raises question.
A core test of a pump-and-dump identification system is its real-world detectability. In Case 1 Fig. As a result of their coordinated efforts a large price and volume spike is visible, beginning exactly at the time at which the announcement took place. The chart depicts the results of a pump-and-dump promoted by the group Moonlight Signal , which was signalled to commence at 4 pm UTC on the 17th of August. Exchange: Binance.
Once again, the warning signals of corresponding price and volume spikes are present, and the system correctly marks the strange activity at the announced starting time as fraudulent. In this case we also observe the price and volume beginning to increase just prior to the announcement time, perhaps indicating insider trading by the group leaders.
The chart depicts the results of a pump-and-dump promoted by the group Moonlight Signal , which was signalled to commence at 4 pm UTC on the 21st of August. The pump announcement in this case was given on the 4th of September , at p. Once again, we observe corresponding price and volume spikes Fig.
The reason for this is that the price continued to climb for a while after the pump, instead of immediately dumping. Thus, we can observe that sometimes the momentum caused by a pump group may actually persist for a period of time in this case about 24 h. The chart depicts the results of a pump-and-dump promoted by the group Moonlight Signal , which was signalled to commence at p. While our system correctly marked the corresponding price and volume spikes at the specified time, it failed to identify them as being the result of a pump-and-dump.
In Case 4 Fig. Similarly, to Case 3, our system again fails to mark the anomalous spikes as a pump-and-dump, for the same reason of the price not dipping quickly enough afterwards. In order to correctly identify these cases in which the price maintains momentum for some time after the announcement, a potential improvement could be made to the algorithm whereby decreasing volume is also taken into consideration.
This paper attempted to introduce to the crime science community the problem of cryptocurrency pump-and-dump schemes. With cryptocurrencies becoming increasingly popular, they are also becoming a more likely target for criminal activity. Cryptocurrency pump-and-dump schemes are orchestrated attempts to inflate the price of a cryptocurrency artificially. We identified breakout indicators and reinforcers as criteria for locating a pump-and-dump and investigated the data using an anomaly detection approach.
We were also able to show that using a limited set of parameters it is possible to detect pumping activity in the data as well as subsequent dumping activity. Moreover, we monitored two pump-and-dump groups in order to obtain several cases of real life pump-and-dump schemes which we then applied our detection algorithm to, in order to demonstrate its performance in real scenarios.
Besides locating potential pump-and-dumps, we found evidence of clustering in the data. Translated to the environmental criminology literature, this pattern resembles repeat victimisation Farrell and Pease ; Kleemans ; Weisel ; Farrell The clustering can be exploited for preventative purposes since efforts can be concentrated towards the clusters, finding out what makes them attractive targets, and implementing strategies to help mitigate potentially nefarious activity.
Consider an exchange which requires additional verification for users trading certain symbol pairs which are determined to be vulnerable. Such an intervention would increase the effort required to trade and hence to pump the vulnerable coin. When considering how to increase the risk, an example could be a system in which the automated detection of anomalous trading activity is used in cooperation with humans. A major challenge for pump-and-dump prevention might lie in coordinating the efforts between private bodies such as cryptocurrency exchanges and government bodies.
While governments are catching up on the problem and have allocated more resources to the mitigation of pump-and-dump schemes, exchanges might have little incentive to cooperate because they benefit from trading activity on their platforms.
Finally, a move towards more government regulation—in our data less regulated exchanges were targeted disproportionately more frequently—might undermine the very concept of cryptocurrency trading as a decentralised exchange without government interference. In the current investigation, we resorted to publicly available data and provided a framework for the future analysis of cryptocurrency pump-and-dumps.
However, several limitations merit attention. First, the accuracy of flagging an alleged pump-and-dump is dependent upon the parameters chosen and cannot be ascertained absent a ground truth of confirmed pump-and-dumps. Our analysis should be treated as a first attempt to place the topic in the academic literature. Second, the dataset only covers 20 days of data with hourly granularity. While this was sufficient for the scope of this paper, future research would want to attempt to collect more substantial quantities of data and at a smaller granularity e.
Third, as with any flagging system, there is a decision to be made how many false positives are acceptable i. Arguably, an exchange would want to avoid announcing a coin of being used for fraudulent activity if this were not the case. This compromise is particularly complex in real-time settings so an interesting alternative avenue for future research might be to move towards the identification of early warning signals that can highlight suspicious trading at a point in time where the costs of false positives are relatively low e.
In order to minimise the likelihood of Type I errors i. Thus, a cost for both Type I and Type II errors needs to be determined, and a balance struck between the two. Thus, a desirable area for future research would be to create of a database of confirmed pumps. While labour intensive to do in a fully manual way, the creation of such a database could likely be achieved through a smart combination of automated and manual tasks e. Such a database could be used as a means of testing the accuracy of a detection algorithm, as well as allowing for the use of supervised machine learning methods.
Two lines of research seem particularly interesting for an extension of cryptocurrency pump-and-dump identification. First, identifying vulnerable coins and understanding the characteristics of those coins that are repeatedly targeted in more detail would allow for efficient resource allocation of detection systems e. Second, moving away from exchange trading data, the modus operandi of pump-and-dumps could be examined in more detail.
A particularly promising path for future studies could be the linguistic analysis of the coordination of pump-and-dumps in online chat groups, on the one hand; and the means by which misinformation about specific coins is spread on, for example, social media, on the other hand. This paper has attempted to provide a first look into research for cryptocurrency pump-and-dump schemes.
Ultimately, it is the hope that the information presented in this paper will serve useful as a basis for further research into the detection of these fraudulent schemes. Bartels, K. Click here to buy the next Microsoft: the penny stock rules, online microcap fraud, and the unwary investor.

So, it is going to contain:. And, of course, no one is going to tell you when to close signals, what is the risk percentage, etc. But, these signals are not common because they have the purpose of giving profits to the person that published the pump signal, but not to the common traders that use paid signals for trading on an exchange.
During our experience with crypto traders, we noticed 2 most common schemes with pump and dump crypto signals, and we will tell you more about each of them below. If you message them to buy a membership, you will get the message with their very bright and friendly welcome message and, what is more important, unacceptably high membership costs. If you are the beginner-trader, you will more likely think that this admin is really very friendly and he is going to guide you through your trading process, and you will be interested in this channel no matter how high the VIP prices are.
In a couple of days the admin writes to him again, sending the same message but the different amount of BTC - the higher one. Usually it starts from 0. And they promise the same - to send back the money and final profit. A user, because he knows that last time they sent the money back, feels okay to send them more to receive higher profits. After the second big payment, users usually do not see their money returned.
The second pump and dump signals scam is really about pumps - the special signals that traders use to receive profits from cryptocurrency trading. The admin, his friends, etc. They start to promise that soon they will post a huge pump coin.
They write the names of those coins, the time of publishing the signals. Then, before posting the signal, they buy a certain coin at a very low price, and after that, they post the signal. Usually, such groups have many paid members, because they set low prices or sometimes are even free to join! Let's say coin LINK has a small market cap and a relatively constant price. The group gives a pump signal and indicates the target price. Relatively small injections are enough for the coin to move the price and draw the attention of real investors to it, who will no longer invest in response to a signal.
And as many traders wait till the coin will cost more more, in the end, they are in a huge loss because pump coins are very weak and can not increase with no outside interference. And you are lucky if the group is free to join and you will not waste your money on the subscription!
We understand that not everyone knows the real sense and schemes of these channels, so we explain everything and advise legit and profitable channels to work with.

The membership fee is very low, and the results of the channel are good. Today we discussed the process of pump and dump Telegram groups activity.
Now you know that there are two main schemes they use to earn money - the first one is a typical but psychologically managed scam, and the second one is the process of how almost all the pump and dump groups work. We hope that this article will help you understand that pump and dump groups can not give you the permanent source of income, and they will not give you a good trading experience for sure - you will only waste your time and money.
That is why, on this page we list our approved channels not to give the pump channels opportunity even to be seen by newcomers who can trust their fake results and promises. With our legit traders, you will be able to form a permanent income and build your own strategy that will serve you successfully for many years. To remind you one more time, will give you the list of successful channels that are listed on our platform:.
Fat Pig Signals. Rocket Wallet Signals. Members are told the time of the pump and the trading venue ahead of time to make sure they are ready, but only told the specific coin that is being pumped just moments before to ensure everyone buys at the same time. The PumpKing Community has over 14, users but the above advert claims that over 60, people will be sent the pump signal as the announcement in question will be shared to Asian channels.
At the allotted time, participants are told the coin and sent a link to the venue where they should start buying in. The pump order coincides with a jump in price for Magi on the Bittrex exchange and unusually high trading volume for the coin in question. After the initial wave of buying, the pump moves to the dump. Those involved in the first wave of buying take to other Telegram channels, message boards, and forums to encourage others to buy the coin in question. Often they will advertise recent news — sometimes something as minor as a new website — or simply say there is a long-term opportunity.
The recent price rise is pointed to as evidence that the coin is hot. Almost always, big returns are promised. As new buyers come into the market, people who originally bought in the first wave of buying offload their coins at the new higher price, hoping to make a return. This wave of selling depresses the price, often to below the level it was at prior to the pump.
Here, in another channel, users are encouraged to start buying VCash, simply because the team behind it have launched a new website. It is not clear whether all of those involved in the pump and dump schemes are profiting from them — if not enough new buyers come into the market, they could be left with a coin that has been pumped to an artificially high price. What is clear though is that people are colluding to manipulate the price, something that would be illegal in most regulated markets regardless of whether they profit.
During Business Insider's investigation into pumping and dumping in the market, we witnessed five examples of the scam in action. There appear to be many more, with Telegram channels advertising pumps or "signals" daily. Regulators around the world are looking at the markets but they remain a "wild west. This kind of manipulation appears rife in the market but is difficult to police. The exchanges are, for the moment, unregulated and so those involved in "pump and dumps" are not technically breaking any laws.
However, regulators around the world are cracking down on the market: China has banned exchanges and the US SEC has repeatedly signalled that it is likely to treat the ICO market like the stock markets. This could spell the end of "pump and dump" schemes. Ben Yates, a fintech lawyer at international law firm RPC, told Business Insider: "The reality is that unless and until effective regulation is brought to bear, pump and dump cryptocurrency scammers will continue to get away with it.
