Congrats ProGame! Almost 50 BTC in one second that's really something. )
Although I've never been tipped by him, I can confirm that ProGame is a good tipper. I've seen he tipped a lot of people with over 0.01 and some with 0.1 even. He's a great member of PD community and I'm glad he won that big eventually because he was losing a lot before too.
It is an incredible game and the guts he had to try those values speaks volume of the indivual and i am sure he has lost many to hit the jackpot and i think that is the highest win from a dice site,whether he tips or not he is a kind of player that every casino likes because of the risks he takes with every roll.
Yes, all gambling sites like to have this kind of high rollers because then only they can make more profit from this casino business. As long as the player plays for longer time on site, then the most likely site is going win and very seldom people will win. No need to spend more to win jackpot but one need to lucky then can win in the beginning itself.
