I could name a names of people on youtube right now who have systematically done what you say is impossible, with videos showing them do it week in and week out, against real casino and rng games. Winning over $250,000 in single sessions a small relatively "dust" balance and working up a couple thousand into way over $100,000 with a "system", you have no idea cos you dont do any research worth paying attention to.
The only reason casinos dont go bankrupt, is because they deny "advantage" players entry, simple!
AND First you need the money to make a high basebet

Why you so angry ?

How would online casinos deny players entry? I would like to know that, you can set a new IP and come to an online casino over and over again, your logic is stupid, as I said if a strategy worked, every single online casino would be bankrupt but they aren't, amazing. I would like to know those names on youtube right now.
You know im talking about real casinos. Why should i tell you ... ill give you 2 clues, roulette and roulette others can tell you if they know.
Anyway last cap for today 70,000 rolls ...
