The 21 million Bitcoin limit is back in the spotlight. And this time it’s not noise—it’s Adam Back vs. Peter Todd. 👀
For those who don’t know: this week, Peter Todd revived his argument in favor of a permanent block reward—i.e., questioning whether Bitcoin should continue issuing BTC beyond the 21M limit to maintain network security in the long term once mining rewards reach zero.
Adam Back, one of the most respected names in the space (and a direct reference to Satoshi in the whitepaper), strongly disagrees. For him, touching the 21 million limit isn’t just another technical tweak—it’s breaking the foundational promise that makes Bitcoin… Bitcoin.
What I find interesting isn’t who “has the right answer,” but what the debate reveals: as the year 2140 approaches (when the last BTC is mined), this conversation about the sustainability of network security will keep coming back again and again. It’s not the first time it’s been raised, and it won’t be the last.
The underlying question is simple but uncomfortable: is Bitcoin’s value in its absolute, unchangeable scarcity—or in its ability to adapt if the network ever needs it?
Which side are you on: are the 21 million untouchable, or should we leave the door open to the debate? 👇
