upgrading in 90% cases = fail
Cryptsy is actually the only exchange I store my coins.. also got a rebate because of it, so that's good too.
I have 100% trust towards Cryptsy, that's because they have always responded and they are always nice towards you.
Support and trust is everything, it overweight the site. I just hope that other exchanges would see that too..
I have to agree Cryptsy support is very good, I was never left in the limbo and yes I had problems but they were solved...
meanwhile several markets still missing at Mintpal.
I've also had some problems with Cryptsy back in the days. One time I cancelled a trade order and my coins just disappeared (wasn't credited back to my balance).
Just made a ticket and they refunded me within some hours - fair and square.
