I am sure in 101% that he plays fake money, but a lot of friends of mine - said the opposite.
After twitch banned stake and other casinos, he deleted all videos and dont even stream anymore, so its 100% proof they he had deal with stake and use free money to play, what do u think?
I know it is hard to believe it. In my case, at first I did not believed that it is a "real" money, but then later on, I am convinced that the money is not fake. You can see how genuine his reactions are and how he behave on his next day stream almost everytime he had a big loss from his previous stream(s).
This guy, Roshtein, is different from other streamers.
So IMO train is a fake money streamer as he isn't actually losing his money and is paid for content. Rosh may have the same deal and fill his balance with his funds but is reimbursed 100% if he loses plus a little extra on top.
I cannot confirm any of this, just my thoughts.
Think about it. Slots are fucking terrible. You're gonna lose most of the time. Who in their right mind is gonna go max bet billions of bets knowing they're gonna lose their ass, if they weren't playing on free money basically?
