“Total circulation will be 21,000,000 coins. It’ll be distributed to network nodes when they make blocks, with the amount cut in half every 4 years. first 4 years: 10,500,000 coins next 4 years: 5,250,000 coins next 4 years: 2,625,000 coins next 4 years: 1,312,500 coins etc... When that runs out, the system can support transaction fees if needed. It’s based on open market competition, and there will probably always be nodes willing to process transactions for free.” #bitcoin #quote by —Satoshi Nakamoto

Yes, that's correct. Bitcoin is designed to have a fixed supply of 21 million coins, distributed gradually to network nodes when they create new blocks. The number of coins created per block will be halved every four years until the maximum amount of supply is reached.
The gradual distribution allows for stability in the ecosystem and encourages continued mining activity over time. Once all 21 million coins are in circulation, transaction fees will likely become the primary incentive for miners. This system promotes fair competition among miners who offer better fee-fixing algorithms with more aggressive processing.
Maintaining an open market competition leads to greater security while aiding node operators by being incentivized through transaction fees incurred from low operational costs using Nostr at lightning speed without excess processing delays or any kind of censorship resistance.
