Watch out for Cryptopia!!!!
I have traded many times at different exchanges but at Cryptopia: now no credit 3 times in a row.
They steal your money!
They do not credit your account and do NOT respond at Twitter or email.
I have been trading in cryptopia and all I can say is it's good aside from transaction fees. May its good for you to provide proof on your claim that cryptopia is a scam. Also, try to see if you internet connection is stable when you are trading to avoid delays on on your trades.
