The total amount of Bitcoin remains unchanged. Bitcoin will be permanently withdrawn from circulation if the holder forgets the private key or dies, so Bitcoin is a deflationary asset. As more and more people forget their Bitcoin private keys and take their Bitcoin private keys to their graves, the amount of Bitcoin circulating in the market will decrease, and this is irreversible.
Theoretically, as long as Bitcoin survives long enough, there will be a day in the future when less than 1 Bitcoin will be left in circulation. Don't worry, this will not affect the function of Bitcoin at all. Because Bitcoin can be divided infinitely. As long as all miners agree, the Bitcoin program can be upgraded to allow Bitcoin to be divided into smaller units. By then, the total number of Bitcoins owned by people on earth will be less than 1. And 1 Satoshi is worth a mansion. The average person earns only two or three Satoshis in his lifetime.
Bitcoin will not suddenly be left with only one, but will go through a long history and be lost bit by bit by people. After someone loses a Bitcoin, he or his children will earn Bitcoin from others through labor. The remaining Bitcoins will soon be distributed to everyone.
The circulation of Bitcoin decreases little by little, and the purchasing power increases little by little. Millions of years later, humans have become an interstellar civilization. By then, the Euro, the US dollar, and the British pound have long become artifacts in museums. On the Orion Arm of the Milky Way, the dotted human colonies still run the Bitcoin network. The buildings of the ancients on Earth have become ruins, but the transaction records of the ancestors of Earth civilization using Bitcoin are still written on the Bitcoin blockchain, unchanged from ancient times! #BTC
