I always hated Cryptsy. Mintpal is clearly the new king!
It all depends if you do volume...
Cryptsy is OK if you do 5 trades/day... and love your tricky Captchas.
I have yet to see a fooking Captcha at MintPal.
Now that the IRS has basically defined cryptos as commodities...
ALL these crypto exchanges TOTALLY fail Reporting Requirements...
It's as if none of these people have ever seen a brokerage account.
The Financial World runs on days, months, and years...
Not of some random number like "recent trades" or "last 20 trades"...
Unless these "exchanges" start producing tax compliant monthly statements at the very least...
They will all get shut down one by one once the SEC scales up the manpower.
