A Bitcoin Core Developer Wants to Rethink the 21 Million BTC Cap — Here's Why That's a Big Deal

WHY IT MATTERS

Think of Bitcoin miners like security guards protecting a vault. Right now, they're paid mostly through new Bitcoin being created (like printing new money to pay them). But Bitcoin is designed to stop creating new coins eventually — there will only ever be 21 million. The idea was that transaction fees (small tips people pay to send Bitcoin) would eventually replace that paycheck. Peter Todd is raising the alarm that those tips currently make up only 0.5% of what miners earn, which is way too low. If miners aren't paid enough in the future, fewer of them will work, and the network becomes less secure — like having fewer guards protecting the vault. The 21 million cap is one of Bitcoin's most important features because it means Bitcoin can't be inflated like traditional money. So even suggesting it might need to change is extremely controversial and worth paying attention to.
