Being a regular customer he knows the man was able to explain much about bitcoin as at that time to him and was able to convince him to give it a shot. Fast forward, young bruh was able to buy bitcoin worth $50 and was stored in a wallet which the man helped him to create. According to him he had the password to the wallet and seed phrase all given to him but carelessly placed it where he can't even remember. This was all in 2013.
That would be about $100,000 today in bitcoin according to ChatGPT and depending on the time in 2013 when you bought them. But that would only be in case he found the keys now, because had he had them all this time he would surely have sold at least some of it.
These type of things happen all the time, even right now. For example, even if we do not talk about "losing" but just not seeing the future, I had 2+ bitcoins that I just used for silly gaming skins, in 2013, that was like a few hundred bucks back then, now it's 180k. Obviously a mistake, but I never regretted it, I always feel that move got me into bitcoin and that is why I am thankful for it. I have lost 6 bitcoins before that, on some exchange that got closed (exit scammed) and many other ways like that.
I have been in bitcoin for so long that I may even have some coins somewhere that I already forgot, these things do happen and we learn to live with it. Doesn't mean I am happy about it, just means I am not sad about it.
