Exactly 13 years ago, on January 12, 2009, the creator of bitcoin under the pseudonym Satoshi Nakamoto made the first transaction in cryptocurrency, sending 10 BTC to cryptographer Hal Finney. Hal Finney played a crucial role in the history of bitcoin, and according to one version, he was the creator of the cryptocurrency. Since then, 700 billion transactions have been made. The first BTC transaction was confirmed in block #170. The cost of the cryptocurrency received by Finney was almost zero. According to him, the cryptographer extracted several blocks on his own personal computer. Since then, cryptocurrency mining has become an industry in which specialized high-performance devices are used, and the hashrate of the network exceeds 170 EH/s. However, currently, the solo mining of cryptocurrencies continues. Yesterday, an unknown miner with an equipment capacity of 126 TH/s included block #718124 in the blockchain. Experts note that the probability of this event was less than 0.0001%. The anonymous miner received a reward of 6.25 BTC. As you know, in 2009, 50 BTC was charged for the extracted block, but this figure is halved approximately every four years. In December 2021, miners mined 90% of bitcoin. Analysts note that the cryptocurrency is expected to reach the issue limit of 21 million coins in 2140.
