Bitcoin's fixed supply cap of 21 million coins is under renewed debate after Peter Todd proposed a permanent, small issuance of new coins to pay miners beyond 2140 when block rewards end. Todd argues this 'tail emission' stabilizes supply by offsetting lost coins and prevents security risks from fluctuating transaction fees. Adam Back counters, calling this proposal a misleading narrative aimed at uninformed users, comparing it to the failed 2026 BIP-110 soft fork. The debate highlights ongoing concerns about miner incentives and network security, but any change to the supply cap would require a hard fork and unanimous agreement, making it unlikely in the near future.
