[I'm really angry at Cryptopia ...]

Don't throw it all on the exchange, many of the coins you mentioned are really broken. Kangeroo Bits is hopelessly broken, I actually was looking at fixing it at one point, it is broken beyond any hope of repair. Fire Rooster dropped dead, there are no nodes anywhere on the planet, you can't really blame the exchange for that.

Lemon is marked on topia's delisting info page as having a non-functional wallet or chain, so it still has a chance, if someone is willing to work on the issue..
