PCs and mining software. The first known Bitcoin commercial transaction occurred on May 22, , when programmer Laszlo Hanyecz traded 10, Bitcoins for two pizzas. However, while Nakamoto was the original inventor of Bitcoin, as well as the author of its very first implementation, he handed the network alert key and control of the code repository to Gavin Andresen, who later became lead developer at the Bitcoin Foundation.
It has managed to create a global community and give birth to an entirely new industry of millions of enthusiasts who create, invest in, trade and use Bitcoin and other cryptocurrencies in their everyday lives.

The news has produced commentary from tech entrepreneurs to environmental activists to political leaders alike. In May , Tesla CEO Elon Musk even stated that Tesla would no longer accept the cryptocurrency as payment, due to his concern regarding its environmental footprint. Though many of these individuals have condemned this issue and move on, some have prompted solutions: how do we make Bitcoin more energy efficient? Others have simply taken the defensive position, stating that the Bitcoin energy problem may be exaggerated.
The Bitcoin mining community also attests that the expansion of mining can help lead to the construction of new solar and wind farms in the future. Moreover, the energy consumption of Bitcoin can easily be tracked and traced, which the same cannot be said of the other two sectors.

The smallest units of Bitcoin, 0. The top crypto is considered a store of value, like gold, for many — rather than a currency.
