Scrypt.cc is a total scam.  I deposited a small amount just to test them.

I always felt it was sketchy, but now I'm sure of it.  I've tried three times now to sell my hashing power and withdraw my BTC.  It always says that the ETA to payment is 20 minutes...for at least 3 days.  Then suddenly there's no trace of the withdraw and it's been re-invested back into hashing power.  Rinse/repeat, but at a lower price now because the cost of hashing power is constantly dropping.

Today I made one final attempt and by the time I finished filling in the withdrawal information, my funds had already been converted back into hashing power and gave me an error message that I had insufficient funds.

They will never allow you to withdraw your funds.  It's complete bogus.
