I usually never bet quite a bit more than a dollar either. You make corresponding profits with such high multipliers only with a lot of luck. If I would bet much higher contributions (5$ or 10$) the profit with such high multipliers would be of course much higher, but I would also be relatively fast at a balance of 0.
Well I can imagine that if we bet above $1 or more above it, of course the balance will run out quickly and we have to have big capital if we want big bets.
In Roobet's post we only see big multiplier wins, let's imagine how much he lost to get big profits?
Of course people will hide it and it can be more than a big multiplier or even more.
What is clear is that when we win with a multiplier the feeling of emotion will be slightly cured.
I would say that it depends on how much money you have. If you have tens of thousands of dollars and gamble with just one dollars, then you are going to end up with something very low in the end, but you will still have money left, but if you have under 1k then it could be very quick for you to finish up all of that money, if it is under 100 dollars then you are going to end up with nothing in few hours.
So, how much you gamble should be based on how much you own. Plus all those "winners" when you see big wins do not show their whole betting history, they just show the big win, when you check the betting history almost no one has a profitable history if they gambled long enough.
