I made several mistakes that resulted in big losses in the past, always because of typing errors and/or stupidity. It all happened at stake.
Several times in the past I played sports bets with btc and once instead of betting 0.01 I bet 0.1 btc, when the price was at 20k. Of course the bet lost, like a NO BRAINER loss. I said to myself this will never happen again, but it did.
1 year ago I bet 0.005 on a WNB game at 2,5 odds, so I thought. Well it was 0.05btc that I bet. Then I saw the mistake and cashed out because I couldn't take the risk. I only got 0.042 or less back.
And guess what, the bet would have won, like always when I cash out. FML.
What's also bad, this was also like 1 year ago, I wanted to make some LTC bets in the casino there. Normally you can choose between fiat and the coin. I thought I had it on fiat and bet 1"$". Well it was 1 ltc, and within 5 seconds I lost like 5 ltc, of course every single bet, even though 50/50 chance, lost. Like always when you bet more than a couple of $ at this site.
You know that things like this have also happened to me, in craps at freebitco.in it happened to me that instead of betting 0.0001 sats I bet 0.001 and that time luck was with me and I won, but it was because I did it as if by reflex because it was in my bed and I did it I think half asleep, of course I woke up immediately, but a few days later I made the mistake again with another amount, but something more or less in quantity and then goodbye to the money, at that moment I lost control, it made me angry , and I started playing with anger, with stress and well, on that occasion I ended up losing all my balance that I had been working on and raising for some time.
It has also happened to me in trading with the zeros and well it has been painful, because I have lost them, and the last time I lost it because I got distracted and well I lost focus and lost, that was like 12 days ago and I haven't I started tading again because I still feel angry with myself, but you know that this happens because one is very careless.
So it could be said that not only has this error happened to you, it has happened to many of us, it personally makes me very angry with myself the fact that it happens to me, and it is something that frustrates me, because at least in I must do the evening calmly, completely calmly so that I cannot or do not make the mistake again. With games it is different, because at least in dice and poker I need concentration, but in other games I need more concentration, the only one in which I don't worry, it's in tragmoendas that spur luck, otherwise I think that there are two games in a casino, as players we must be very focused, because any mistake like that normally won't make you lose faster than normal and that's not pleasant at all, For now the things that are done are much smoother, take life calmly and when it comes to tading, it is preferable at least for me to concentrate too much and practice first with the demo mode, because if I make a mistake there it doesn't matter, on the other hand in real way like this.
