Its a huge ammount to put at bankrolls from casinos, even knowing they are profitable its a huge risk to make just those investment, with 100k i would make my own casino, soo the risk would be reduced to zero, and who knows maybe build an exchange, since this are the two places where are the most coins being spent.
I think too stupid to use all your money just to put it in a gambling site, because with money
$ 100k you can make a gambling site itself? of course it would be much more profitable right ?
