Why do we need these LTC or DOGE markets, if it is impossible to withdraw coins from the exchange for weeks and months?
I have been using Cryptopia for a few years now, and have never had a problem withdrawing anything at all.
Always check the wallet is not in maintenance first though

I highly recommend Cryptopia and now that LTC and Doge markets are back, its almost perfect in my opinion
You're lucky. You do not have to give children's advice in style: check if the wallet is active and has connections, because it has. The problem with withdrawals occurs in some currencies when you try to withdraw the entire sum in one transaction, for example for a masternode (read earlier in this thread what it looked at marvel213). The most annoying thing is, that you wait 40 days for a support response that gives nothing and that does not solve the problem. It looks like Cryptopia blocked larger payments (maybe they lost liquidity because someone robbed them) or launched masternodes from customers' funds.
What about the fact that, as Lafu claims, they hired new people, since these people can do nothing? Can the support employee not just cancel the transaction that did not go to the blockchain and allow the customer to try again? It all stinks at a distance and shows that something is wrong with Cryptopia.
