This isn't true. OP may be confusing things like this - https://www.gamblingcommission.gov.uk/licensees-and-business... - as saying that crypto is regulated as gambling, but it's not.

wait if crypto is gambling, then they don't tax the proceeds, right? but I'm pretty sure they tax it as capital gains..... so it's gambling for advertising purposes but capital investment for tax purposes...

I suppose the law is an ass.
