The worst mistake I've ever made is using a bot to automate my bets. I tell you, I still regret it until today because I lost Lot's of funds even funds that were not in bankroll
me too, i have this bad experience in two days ago and until now i am not gambling again, maybe i will gambling in next weeks but i am not loss much of satoshi as you. from this, i think i will not use auto for my bets as i don't want to get bad experience again.
and that is the reason that i am trying to convince my friend to play gambling under a limit, because if you start losing money in gambling or you made a worst mistake in gambling, you my not lose all your money as a whole. your planing and good strategy will protect your from losing a big amount of money in short period of time.
That's how you gamble with direction, you cannot just play there without a specific game plan, gambling is very risky and you can lose all your money if you follow your emotion and you chase bets. Worst mistake that is possible for us is when we use the money not intended in gambling, believe me, you just created a big problem that will accumulate to a bigger one.
