Yea, the government might be able to trace who owns what coins... but how can we... how can we as regular people avoid buying some centralized piece of crap coin, with absolute certainty.
If you want to avoid 100% from shitcoins, you really have to avoid all ICOs. There are no really set of rules and requirements that you can tell that a coins is legit, scam, successful or a failure. Everyone investing knows that this is all 50/50 chance that you get a legit and successful coin of out ICOs.
