They have locked my account and stole what was remaining in my account, including a relatively large withdrawal that was pending since Dec 23rd.

They are not suffering technical problems folks!!!

The delayed withdrawals is money they are spending .. perhaps it is short term need, or str8 up theft ..  seems they are simply transitioning into a Scrypt.cc-style ponzi - new deposits fund delayed withdrawals - periodically a withdrawal will disappear, and when you complain enough, your account will be closed without warning.

Cryptsy .. Scrypt.cc .. I wouldn't be surprised if it's the same mfers.  Anyone dumb enough to give Mintsy money?  Their baby too .. how'd that work out for ya?

A few good alternative exchanges ..

alurEX
poloniex
bittrex
bluetrade

Good luck!
