Didn't I tell you that "the personal stats could not tell me anything, or let me send you the details on it because I meet the same problem again recently though the problem is not always happened"?

I also told you that "I have also sent a contact form under FAQ section. It is about I lost 0.05 BTC (but I am not sure how about I lost). I have not done anything but the funds suddenly disappeared. It would be appreciated that we could communicate by email. Thanks". I mean I do not know why it was lost because I did not do anything on those funds yet. That's why I said, "It is because I do not always have that problem, but I will send you the details on it very soon. Sorry for bothering".

If you could not find where the problem is, it is fine. Just a lesson to me - do not press the max button if you have large amount on your account. I hope it won't have any problem in the future, or I could win a jackpot to gain back my loss.
