Bitfinex’s figures put Bitcoin (BTC) at a 0.4% annual issuance rate after a 2028 halving and Ether (ETH) supply growth at 0.8% to 0.9%, leaving the Bitcoin rate lower.
Each time Bitcoin’s chain reaches another 210,000-block threshold, the protocol halves the new-coin subsidy paid to miners. The interval generally takes about four years to complete. The April 20, 2024, halving left miners with 3.125 BTC for each block.
The estimate concerns the pace of new issuance, while earlier EconoTimes coverage of Bitcoin’s 21 million-coin cap examined cumulative supply.
Block production determines the calendar timing of the next protocol cut. Bitfinex estimates that milestone for 2028.
