Bitcoin Supply Limit Debate Heats Up Between Pioneers

Bitcoin's fixed supply limit of 21 million coins is at the center of a heated debate between pioneers Adam Back and Peter Todd. The issue revolves around what happens when block rewards end in approximately 2140, which could lead to miners reorganizing blocks for profit.

Todd suggests introducing a 'tail emission' - a small permanent reward - to maintain network security, but this proposal is met with opposition from Back, who views it as a threat to Bitcoin's core economic principle. The debate highlights ongoing concerns about Bitcoin's long-term security and the need for broad consensus and a hard fork to implement any changes.
