Bitcoin Mining Will Rely Heavily On Transaction Fees After 21 Million Supply Limit

Bitcoin mining is expected to continue even after the cryptocurrency's maximum supply of 21 million BTC is reached. The block subsidy, which currently rewards miners with newly created Bitcoin, will gradually decrease and eventually reach zero. This shift in mining economics means that transaction fees will become increasingly important for miners to secure the network.

According to Vikas Gupta, Country Manager, India, Bybit, 'Bitcoin mining does not stop when the 21 million supply cap is reached.' Instead, miners will continue to validate transactions and add new blocks to the blockchain, but the nature of their reward will change. Transaction fees are expected to become more valuable as the block subsidy declines.

The transition in mining economics has already begun with each halving event, where the block subsidy is cut in half every 210,000 blocks or roughly once every four years. This process will continue until the final Bitcoin is mined around 2140, when the block subsidy is expected to reach zero.
