It makes me laugh when I'm realizing my promises to myself to not gamble again whenever I'm losing in all in bet. After that when I have bitcoin again, I would think to gamble it first and ending up losing all of it

Now I had control to myself but still gamble a few bets sometimes
You are not the only that struggles with these promises. You can neutralize yourself but you can never say that you will quit, right?

We may promise to stop shortly after experiencing bad things in gambling, but over time, the intentions will gradually be eroded by the dream of winning or the desire to pursue the loss that can arise at any time. We can't just stop the activities we've been doing for so long.
Some are success in stopping themselves to gamble but most can't just resist on how hard it is to remove the addiction.
