I have had repeated problems with Cryptopia over the years. They don't maintain their site properly. I really don't see how they justify charging fees to use their exchange.
I made a test send of 2 BWK to Cryptopia which now has over 1700 confirmations but they don't credit me with it.

Quite a few months ago I sent over 600 SIGT to their "exchange" and they never showed up. I sent a support ticket and they told me they had de-listed the coin, but they hadn't bothered to remove the deposit wallet addresses from people's accounts. They just put some notice in their "news" section about de-listing SIGT but who ever reads some separate news section on an exchange? As far as I'm concerned they stole my coins.

Now they seem to have stolen my 2 BWK too.

Given that they are (although crap) the biggest exchange trading BWK, it would be nice if the BWK dev/s would contact them and try to kick their asses a bit.
