So far the only coins we know are affected for sure is ETH and a large amount of ERC-20 tokens. But to be honest, I think that which coins are affected doesn't really matter. If Cryptopia goes bankrupt because of this, we most likely can say bye-bye to our coins. If they don't but can't pay back all users, whatever is left may or may not be split between users. I highly doubt they will only let the holders of affected coins take the whole hit if they can't pay the whole amount after their own pockets .

As for news, they are most likely under strict instructions from law enforcement not to talk about anything (even Cryptopia themselves may not know everything police knows). It's for everyone's own good to talk about nothing until they know exactly what happens, as news could potentially tip off whoever did this.

For now, all we can do is hope Cryptopia have a "crisis fund" set up, and will simply refund every user once the investigation is over, and they will pick up where they left off (minus a lot of their reputation).
