I have the feeling that ltc casino is one of those casinos that hires streamers who play fake money with a practically no money limit account. People watch them play live and they lose large sums and without any problem make next (fake) deposits until they hit some big win. Of course, they do not lose anything, because the account on which they play is prepared by the casino especially for them.
Yeah, most of the streamers play with "fake" money and they are paid by casino to promote their slots via youtube and other channels. Not saying that this is the case with ltccasino, but I know for sure that most streamers don't risk their own money with such a large bets per spin.
