A total of 21 million Bitcoins will be issued.

About 19.7 million coins have already been mined.

A little more than 1.3 million Bitcoins are left for mining.

The last coin will be mined around the year 2140.

Halving reduces the reward for mining every 4 years.

In 2024, the block reward decreased to 3.125 BTC.

About 20% of Bitcoins are lost forever due to forgotten keys.

Mining difficulty is increasing, raising the costs of extraction.

Satoshi Nakamoto's last public message on the BitcoinTalk forum was sent on December 12, 2010. In this message, he discussed the issue of DoS attacks on the Bitcoin network and the need for software updates. In later messages sent to Mike Hearn and Gavin Andresen, Satoshi hinted that he planned to step back, transferring the responsibility for the further development of Bitcoin to others.

Hal Finney, an American computer engineer and renowned activist in the field of cryptography, was one of the first to adopt Bitcoin. He downloaded the Bitcoin software shortly after its release by Satoshi and quickly became involved in its testing and development. On January 11, 2009, just a day before receiving a transaction with bitcoins, Finney tweeted about Bitcoin, highlighting his early involvement and enthusiasm for the project.

Currently, the balance of the genesis address is 99.72 BTC, amounting to approximately 7.3 million dollars. Interestingly, the 50 BTC originally obtained for mining the first block cannot be spent. According to Charles Hoskinson, this inability to spend the funds may be related to the fact that the transaction of the genesis block's coinbase was not added to the global Bitcoin transaction database, although it remains unclear whether this omission was intentional or an oversight on Satoshi's part.

One of the most significant parts of Nakamoto's legacy is the genesis block of the Bitcoin blockchain, which he mined to receive a reward of 50 BTC. The wallet address associated with this transaction, "1A1zP1eP5QGefi2DMPTfTL5SLmv7DivfNa", is perhaps the most well-known and has been the focus of blockchain researchers. It has been confirmed that this wallet, as well as another address "1HLoD9E4SDFFPDiYfNYnkBLQ85Y51J3Zb1", used to send the first Bitcoin transaction, is linked to Nakamoto.

The largest holder of bitcoins is Satoshi Nakamoto, the creator of this cryptocurrency. Estimates of his assets vary, but on average it is believed that he has about 1.1 million BTC. This amount has not been moved since the creation of bitcoin and remains in the original addresses

Одной из крупнейших майнинг-ферм в мире считается ферма, расположенная в Монголии, в специализированном индустриальном парке. Она была построена компанией Bitmain. Ферма настолько большая, что для её обслуживания требуется несколько смен, в каждой из которых работает по 50 человек.

The probability of mining a bitcoin block with an old computer is extremely low. The power of modern ASIC miners used for bitcoin mining is orders of magnitude higher than that of old computers, making the chance of finding a block virtually zero. Even if you have the fastest graphics processor, the odds are negligible.

In 2009, miners received 50 BTC for the extraction of each block of Bitcoin. In the first year, approximately 1.1 million Bitcoins were mined. Since mining was relatively easy and the reward was high, a significant amount of Bitcoins was mined in the early years.
More details:
Block reward:
In 2009, miners received 50 BTC for each mined block of Bitcoin.
Amount of Bitcoins mined in 2009:
In the first year since the creation of Bitcoin, approximately 1.1 million BTC were mined. This occurred before the first halving, which reduced the reward by half.
Ease of mining:
In the early years, Bitcoin mining was significantly easier and more accessible than today, allowing miners to obtain a substantial amount of coins.
Lack of significant competition:
In 2009, there were not as many miners as there are now, and consequently, there was not as much fierce competition for the reward.
The first 210,000 blocks:
The first 210,000 blocks provided a reward of 50 BTC for each.
Value growth:
Although Bitcoin was worth very little in 2009, its value has significantly increased over time.
In 2009, anyone with a computer could participate in mining and receive rewards in Bitcoins.

The largest holders of bitcoins continue to be Satoshi Nakamoto, as well as various corporations and government entities. Among the companies, MicroStrategy, Tesla, and Marathon Digital Holdings stand out, while among government entities, the USA, where bitcoins were confiscated, particularly from Silk Road users.

BFL was the first company to announce its ASIC-based miner. Confidence in success was largely based on the company's previous achievements in FPGA miners.
In June 2012, BFL began accepting pre-orders for three types of miners: $149 for Jalapenos, with a performance of 4.5 GH/s; $1299 for SC Singles at 60GH/s; and for $30K you could pre-order the monstrous SC MiniRigs with a performance of 1500GH/s.
At such prices, these miners could mine 20-50 times more bitcoins per dollar of investment than GPU or FPGA miners. The total amount of pre-orders just on the first day exceeded $250K, and the activity of customers remained high for a long time. This was more than enough to cover substantial expenses for chip design and the manufacturing of lithographic masks for the 65nm process, which are estimated at $500K.
Each chip produced by BFL contains 16 fully unfolded pipelines for SHA256 computation, which is equivalent in performance to 16 mid-hi-end FPGAs packed into 1 ASIC. At the same time, the size of the chip was only 10x10mm in a BGA package.

Ravencoin (or RVN for short) is a virtual coin that began mining for the first time five years ago. Mining of this cryptocurrency is implemented on UTXO technology, and the blockchain operates on the Proof-of-Work consensus algorithm. During its relatively short existence, Ravencoin has twice marked a change in the mining protocol: a year after its launch, the transition from X16 to X16Rv2 was made, and in 2020 RVN switched to the KawPow algorithm, which was specifically modified for the ProgPow algorithm, available for mining on most modern ASICs. Initially, this algorithm was developed for one of today's most popular cryptocurrencies, Ethereum, but during its implementation, the developers decided to switch from Dagger Hashimoto directly to PoS mining. The result of this decision was the launch of several peer-to-peer networks based on ProgPow. After some time, this algorithm was adapted for mining Ravencoin.

In May 2010, an announcement appeared on a cryptocurrency forum. Hanyecz offered to exchange 10,000 bitcoins for 2 pizzas. At that time, the value of the cryptocurrency was $41. This was the first purchase of a physical item with digital money.

Now, every year on May 22, crypto enthusiasts around the world celebrate Bitcoin Pizza Day. They remember Laszlo Hanyecz and his deal, and as a festive dish, they eat pizza.

One of the first holders of bitcoins was Martti Malmi. In 2009, he sold the 5,050 coins he mined for $5.02, and a few years later he bitterly regretted his hasty decision. Now, such an amount of cryptocurrency would have made him a billionaire.#bitcoin

In Russia, there are about 13 million cryptocurrency users (approximately 9% of the population), including at least 1 million active users whose total daily trading volume exceeds 10 billion rubles. Russians are involved in the development and management of large blockchain projects, and in regions with accessible electricity, the capacities for bitcoin mining are increasing.

In May 1997, Adam Back proposed Hashcash, based on a proof-of-work system, to counter spam and DoS attacks. Subsequently, a similar system in another implementation became part of the procedure for creating new blocks in the Bitcoin network.

On January 3, 2009, the first block was generated, for which the first reward of 50 bitcoins was issued, and the source code of the client software was published. The first transaction involving the transfer of bitcoins took place on January 12, 2009 — Satoshi Nakamoto sent Hal Finney 10 bitcoins. The first exchange of bitcoins for national currency occurred in September 2009 — Martti Malmi sent 5050 bitcoins to a user with the alias NewLibertyStandard, for which he received $5.02 in his PayPal account. NewLibertyStandard suggested using the cost of electricity spent on generation to evaluate bitcoins.

In the document "Bitcoin: A Peer-to-Peer Electronic Cash System," Satoshi Nakamoto outlined the fundamentals of the Bitcoin network, including:
Decentralization:
The absence of a single center of control or management over the network.
Peer-to-peer network:
Transactions occur directly between users, bypassing intermediaries.
Cryptography:
The use of cryptographic methods to secure transactions, ensure anonymity, and prevent counterfeiting.
Consensus mechanism (Proof-of-Work):
Miners solve complex cryptographic problems to validate transactions and add new blocks to the blockchain.
Limited supply of bitcoins:
The maximum number of bitcoins that can be mined is capped at 21 million.
Public ledger (blockchain):
All transactions are recorded in the blockchain, making them visible to all network participants while maintaining user anonymity.
This protocol and the first version of Bitcoin software built on it laid the foundation for the development of cryptocurrencies and blockchain technologies.

The identity of Satoshi Nakamoto, the creator of bitcoin, remains unknown. This is a pseudonym used by the developers who created bitcoin. Various sources have speculated about who might be behind this pseudonym, but none of these have been confirmed.
