I have done many mistakes that prevented me from winning big amounts, the worst one was a zero bet on 10000x limbo multi while I was trying to bet $3. The last misclick happened 3 months ago, I accidentally clicked the max bet button next to the double button on the gambling website, and ofc the result was 0.2x on plinko. Such things can happen, what we can do is to be careful and enjoy gambling as a fun activity while hoping for the best. Just my 2 cents.
Such mistakes can be very infuriating as sometimes they are not really your fault and instead it was the mouse or your keyboard the ones that failed at that critical moment and yet you are the one that has to suffer the consequences of such failure, another factor is that once you have been doing something for some time you no longer put to it the same level of attention, so if you have been gambling for hours it is way more likely that you could miss a click and use the wrong multiplier or make a bet you never intended on making.
