Bitcoin is NOT mathematically limited to twenty one million bitcoins.
I do not support raising the cap at this time but if we had overwhelming support like we did for Segwit we could raise the limit to any number we could dream up.
I would have no issue changing the code to allow a 1 bitcoin reward for every block forever... to ensure a strong distributed mining community.
I understand this must sound like blasphemy to the majority of the community but it irks me to see such a false statement about bitcoin repeated over and over again in every Bitcoin youtube video out there; there has to be a better way to phase it.
Well, it is currently mechanically limited to 21M, and I think that's all anyone talks about when they say that Bitcoin is limited. I have heard a ton of discussions about having a fork to change the maximum amount of Bitcoin, and they've been met with the typical comments of "that can't work", "it would ruin the trust in the blockchain", etc. And it makes sense, really. Halving forever would hypothetically be great for the value of Bitcoin, on paper, since the value would double every 4 years (in a perfect world, that is) and we would be able to reap the benefits of the mechanics of the blockchain rewards. Having one BTC/block forever would interrupt that balance, to an extent.
