Cryptsy is a perfectly cromulent exchange. But like most things in our little universe, have limited resources to deal with what has bloomed into a billion dollar economy.
Crypsy has always dealt with issues relating to deposits and transfers for me in a timely and responsive manner. I would recommend their services to others - BUT:
* Do your research.
* Dont invest more than you can lose.
Maybe they'll figure it out.
Mtgox is still extremely shady and people use it.
