If you choose to upgrade to a 1.1 account with 3 withdrawals a day, they will let you do that for about 3 or four days. Afterwards, they will continue to say you're at your daily withdrawal limit and won't let you withdraw. If you complain, you will be ignored. If you threaten to sue, they will deactivate your account. Don't waste your precious Litecoin. Use it on something more worth it. They just take money. Did you know that you can't upgrade your account with the money your account has been mining? That makes me think that they aren't mining anything. If you can't purchase anything from what you've already mined, then the account is worthless. They don't trust it so you shouldn't either.
