Mate it's not only your unknown mistake but the whole world has to, plenty of my friends lost their crypto by forgetting the phrase, selling in depression, etc
So happened to happen I think it's again golden to invest in before too late.
In this case there have been many examples but strangely there are still so many people who do things like this.
Even though when they are not too sure about bitcoin then don't be here because this will only harm themselves. Many of them say they regret selling bitcoin when they are in a panic but when they see bitcoin drop in price their panic increases again and again.
The mindset needs to be changed a little, I think, because if things like this keep happening, it's not a profit you get but a loss again and again.
