I pity for your loss as it was an honest mistake on your part. From this experience, I hope that before you bet that amount of bitcoins, you should double-check everything as it will be very costly on your part if this situation happens again.
Another thing, I hope this experience does not affect your mindset since most people try to recover their loss by gambling again and then the endless cycle continues. Move on and grind again to earn that much bitcoins.
Gamblers are human that possibly made a mistake unless you are an AI robot that only had zero percentage of doing mistakes.
Just like when I was playing poker before, instead, my decision is to fold my cards but my lazy fat finger chooses the check button and it ends up losing to me.
Situations like these, we tend to take it for granted until all hope is lost and we suffered the consequences. That is also why double-checking everything is the key towards preventing mistakes that would be very costly in the long-run.
