I don't think so, why?

The answer is rather simple because I haven't seen any success stories until today from other investors and such investments are known already for quite some time.

If this will be a successful investment, there will be some info shared on the internet, but all I can find are old threads, mostly abandon after some time.

It is enough to read comments in this thread to know that investing in a casino bankroll is very rare and I don't know personally any Bitcointalk member who actually made a significant profit on it.
