The beauty of the free market is that people are free to move their custom. And businesses are free to set the limitations necessary for profitable enterprise.
Some banks have decided that the risk to having to support customers who engage in risky behaviour is too high. There are literally dozens of free banks in the UK, and it is incredibly easy to switch provider.
Voting with your feet doesn't work. Moreover, banks or credit card processors shouldn't be the arbiters of what you should be allowed to spend your money on.
I am free to do my business, they are free to not take my business. We are all free.
I'm not particularly pro-crypto, but it's an interesting question that we haven't answered very well. It's clear to me that the state shouldn't stop you doing anything risky with your money - that also means stopping people starting businesses. But where do you draw the line? Problem gamblers often funnel every penny they have into betting sites - losing their house in the process. Wall street bets makes it clear that leveraged stocks can cause the same problems. Should we ban them too?
Really? This doesn't seem to match my experience.
The "society" made a profit.
Banks and Megacorps?
Are we all going to just forget 2008 and the simple fact that this technology was created to counter the UK's baiput policy (it's written in the genesis block!) and subsequent inflation tht is due to the rampant increase in money creation PRIMARILY made to bail-out businesses who couldn't or didn't have any savings and were on the verge on bankruptcy at the onset of COVID? The people got crumbs by comparison (extended UI benefits and some never got them at all) and were allowed to enter a roaring hot stock market created by tis glut f Capital pumped into the system and busineses lookign for yield any where they can find it and the minority of this sector (home owners) benefited from the sky high real estate appreciation boom, but it's peak tech-bro to say it was the average person who was the benefactors of any of this (some Industries were completely obliterated and many died in order to return to work despite being deemed essential workers) when it's clear it's the parasitic banking and corporations who are the ones that benefit the most.
I agree that 'crytpo' has been a misused moniker to describe the entirety of cryptocurrencies, but if you have anything but cursory knowledge on any of it and can resist letting yourself be swayed by click bait-headlines you'll realize that it's Bitcoin separated from the rest of crypto.
People can play Ponzi schemes as they like, banks probably should not be involved.
Those who don't want banks involved in their lives are free to adopt some other form of exchange. This may be considered irony.
