1 The maximum number of coins that will ever exist in the lifetime of the cryptocurrency.
2 The amount of coins circulating in the market and held by the public. Data at the time of writing (28/12/2023).
3 Bitcoin mining rewards will be halved every four years, ensuring that fewer Bitcoins will be added to circulation until the very last Bitcoin is mined. The last Bitcoin is expected to be mined in 2140.
4 Since the block time of the network is about 10 minutes, you can calculate that the time between halving events is a little less than 4 years. Calculation: 210’000 blocks = (210’000 * 10) minutes or 3.9899 years.
