I'm monitoring the situation there for several days and weeks. Cryptopia has massive problems to credit deposits and execute withdrawals for a while now.
Deposits usually show up a few hours later after they have been confirmed on the blockchain. But this only, if you open a support ticket to remind them to do so. Official policy is to answer tickets withing 20 (!) days, or at least so they say on their website. However they obvioulsy read them and react, even though no ticket is answered.
Today I believe we entered the next level. Withdrawals are stuck in Cryptopia. Status says Pending for several hours, then changed to Processing after I opened a ticket again, but still no withdrawals occur. This happened for BTX and ONION and not only once.
I can only assume that there are real problems going on with this exchange. So trade very carefully or move elsewhere, but sometimes this is not an option. And as always, never leave any funds on any exchange longer than absolutely necessary!
Happy trading :)
