Not really a "shitcoin", a coin has to be actual shit to be a shitcoin. Fortunately for shitcoins there's a lot more of them than real deal coins, so if someone's a shitvoiner there's plenty to choose from. If you're only into real deal stuff there's like 5 max.
Governments will never allow it... We aren't really concerned about that lol. If it proliferates, good, if not, I can still use it. It exists, it is useful, that's really all it takes, that and time.
