I was using Bitcoin as money back in like 2011 or 2012 buying things online. It was never an asset to invest in, just like cash isn't an asset. Investing in Bitcoin is called savings. Are you suggesting that people should be able to use USDT on nostr? Because monereo litecoin and doge have such a small number of users and I've never heard of any other crypto actually being used as money.

I think regular credit or debit card payments for services would help reach, as would a nip that allows users to specify what crypto they will accept. Let the free market decide what's better. The decision to be Bitcoin only is a principled decision, but like overlapping venn diagrams it selects for a smaller subset of users. Some of the big apps require kyc to use zaps, so defeat the point of permissionless money. They could be good fiat to Bitcoin onramps. We set up to be Bitcoin only, but all the people we reached out to IRL ignored that and payed cash or didn't come back.
