Again I'm not going to post links to all the cryptopia scams you can use Google and figure it out for yourself
You been warned. Just like everyone else has. Now if your Coins get stuck and you lose money don't complain you have been warned
I have yet to see any proof of a SCAM rather than an over stretched exchange, I have googled, and have searched here, and I've read reddit. While I have found plenty of example of an exchange stuggling to keep up, and maybe not handling things brilliantly, I have yet to find any proof of wrong doing.
The Reason BWK wasn't in the list of coins, is because it is now mostly fixed, there is a small glitch that you need to give your wallet a shake for the balance to show up.
