I expect that Elon or some other famous person is going to use Dogecoin again to scam their fans and make a quick buck in the near future.
I like that Ethereum's system changed to use far less energy and thus emit less carbon.
I guess Monero can be useful if you want to buy drugs online or whatever, which I'm fine with.
I know that some people feel really strongly about crypto, either positively or negatively, but I'm mostly disinterested. It's not going to become a particularly useful currency any time soon and it's way too volatile, so if I ever decide to invest in something I'll pick normal stocks instead.
