I also thought it a good idea at one point. I've since been convinced otherwise.
BUT, I do think we need some way for intolerant people to be stripped of the political power of the vote. I just can't figure out a way it could possibly be implemented without being weaponized against the marginalized. It may be better to implement it and attempt "constant vigilance" -- it seems like there are already necessary system that can be so weaponized that still do more good than harm.
Last time I checked, BTC transaction fees were prohibitively high to pay for 80$ AAAA games with them, and WAY too high to pay for a 5 USD single-developer itch.io game.
I haven't looked at other Crypto in a while. I made some money off BTC, but I think it is wildly overvalued for a long time, and I've been disappointed in how un-currency-like other alternatives were, even those that have been around long enough that they are unlikely to be rug-pulls.
That said, if you need to get paid and Visa/MC won't let you use them, I'm not going to attack you (too hard) for accepting Crypto. They are bad systems, but we live in Captialism, so you gotta get paid. They might be the least-worse system that is global and isn't Visa/MC. I'm unlikely to buy your product that way, tho; I'm more likely to pirate than I am to participate in cryptocurrency again.
