As far as i know, in btc-e, for exmple, there is no limit on how many bitcoins you can trade each day, there are some limits on how much money you can withdraw per day with paypal but not in banks.
It seems btc-e.com have already changed that policy they now have a withdrawer limit and delay fund more than usual now.
Dude, that's what i said, i said they do not have TRADING limits, you can sell 100 or 1000 bitcoins for dollars, they do have withdrawals limits.
