I doubt it, he needs to let a few people withdraw some btc, tempt them back with "cheep 'KHS' nomnomnom" and when they work out just how much richer they are going to be by 're-investing' they'll do what they are programmed to do, which is send it back in to the scam.

Then the next lot are selected for the same treatment by letting them do a withdraw for a rinse-and-repeat demonstration of human stupidity.

Once it has been done enough and there's a good enough number of 'victorious' fanboy posts then the game can continue on for a bit longer, as long as withdrawal requests don't outpace deposits of course. If they do, "Oh noes we wuz haxxored. Again".
