Cryptsy is notorious for delay in deposits when a coin is dumped in other exchanges. They halt the deposit citing bullshit reason. They pump and dump dead coins. They were the first altcoin exchange but for unknown reason they are not interested to upgrade their software. Before mintpal, bittrex they were the monopoly and controlled all the pumps. The only good thing is they do not drop the dead coins easily even when there is no volume.
The number one reason we get bad exposure on deposit times is the way our security algorithm works. You'll find that old timers and verified customers rarely complain where a brand new account with no history will have delays.
Other times such as the big DOGE rise to power the DOGE wallets and our system didn't like the 200 tx's per block all coming to the Cryptsy wallet causing issues we had to rewrite how we handled that.
As far as upgrading we are consistently upgrading and working to roll out an entirely new backend and UI. Unlike some competitors we wont roll this out before its ready and risk losing our customers funds.
Best reason to use Cryptsy were here to stay great security and great people working here. If you tried us before give us a try again. If you dont like the security delays get verified its fast and free gives you FIAT markets etc.
