Bitcoin's 21 Million Cap Debated: Permanent Issuance Proposal Sparks Controversy

The debate about Bitcoin's 21 million cap is heating up as miner remuneration becomes a pressing issue. With only one million BTC left to be mined, developer Peter Todd proposes introducing a permanent issuance to compensate for lost coins and ensure miners' income.

Todd suggests that the introduction of a small permanent reward would allow Bitcoin to exceed its current limit of 21 million units. He argues that this would stabilize the available supply since coins are constantly being lost due to their owners losing private keys, offset by new ones appearing.

However, Adam Back, Blockstream's boss, strongly opposes this idea, warning against the risks involved in modifying Bitcoin's rules. He believes that the arguments used to promote such a change could be used to push for more drastic alterations down the line.

To implement any changes, the network would need to accept a hard fork, which could potentially create a new chain with its own rules and supply, rather than the original Bitcoin version.
