Bitcoin mining reaches 19 million BTC

It turned out that the supply of virtual currency Bitcoin, which has been in operation since 2009, has reached 19 million BTC.

Bitcoin nears full supply with 19 million coin milestone

Bitcoin is a virtual currency created by Mr. Satoshi Nakamoto. For Bitcoin, transaction records are recorded in the ledger approximately every 10 minutes. In order to check the integrity of the records, a huge amount of calculation processing was performed on a volunteer computer network, and among those who performed the calculation processing, one who succeeded in adding to the ledger was newly issued Bitcoin. It is given as a reward.

As of April 2022, when the mined amount reached 19 million BTC, the reward was 6.25 BTC per block, which is worth more than 35 million yen.

With this, the remaining amount is less than 2 million BTC, but the amount of Bitcoin mined is adjusted every 4 years, and it seems that it will reach 21 million BTC around 2140.

By the way, the wallet may be dropped and lost, but even if the owner loses the private key, the information 'where it exists' remains, so the 'key of the box that was saved' is to the last. 'I can't open it because I lost it' does not mean 'it disappears'. In this way, it is believed that there are 3 to 4 million BTC of Bitcoins that are already permanently locked.
