There is a huge problem with Scrypt.cc. Withdrawals.

The BTC appears on your withrawals list, you click the confirmation email but the payment never hits the blockchain even though it is deducted from your account.

That has been my experience. About one time in four or five the money hits a black hole and support never answer or fix it. I lost more than I made there because of this withdrawl bug / design feature, so I got out what I could and fled.

I think it is to do with hitting the withdrawl confirmation link from a different device to the one you are currently logged in from.

Yeah, you could avoid doing that, but the fact is the webmaster neither knows nor cares.
