Wow, I don't think that will happen to a gambler who can only spend a small amount of money each week, like me.
Yes, it won't happen to a simply and average joe like us.
I don't really understand, how do you lose 20k
(trying to get some big wins by buying 'bonuses' instead of spinning the spins)? If you don't make a spin, then how can you get a big win, by you buying a bonus, I think it's the same as you doing a spin, right? Or can you say, you expect a jackpot?
I can't imagine, if you only expect the jackpot, then how can you keep spending your money until it reaches 20k? I think it's something I can't do,
instead of expecting a jackpot why not just normal bet with betting options with big odds, I think it will be a bet with lots of trials which of course, the chance of winning big is very open.
Maybe he goes to max bet every spin and chasing that big jackpot or bonus rounds. Unfortunately, when you are playing high stakes then your decision are very clouded and you want to just go on without realizing how much you've lost already until it's too late.
Unlike just average gamblers wherein we wanted to bet huge, but we can't. But in any case we have big money, for sure we will have the same strategy as the OP.
