Hello
One day, a few years ago now, I had ~100 bitcoins on Old Usb Key.
I didn't remember having them, as I'd had them at the very beginning. This USB key was lying around in a drawer, as I imagine a lot of people have
I remembered that I had a Bitcoin wallet not long ago and I tried to find my USB key, without success.
This story makes me sad, because if I'd known, I'd have been more careful!
Moral: be careful with your stuff, even if it's old :p
100 Bitcoin, that's $6.8M Bitcoin we are talking about here. If I'm in your shoe and Bitcoin experience a bull run, I wouldn't be able to eat because that's a life changing money right there. However, looking at how Bitcoin has had its up and down, don't you think you might sell some or sold during the last bullrun, just saying.
I think situation made you not take the USB so serious, if it was a hardware wallet you bought for like $50 in 2010, you would have handle it with proper care and not put it anywhere but a USB key should be less than a dollar in 2010. More lesson for people who are just coming to buy Bitcoin now at this price, in 14 years from now, these post will be use as reference how people some people has loss access to their Bitcoin.
I also think that if you have use Bitcoin core with some private keys back then and properly backup, it might have save you when you loss the USB key but I still don't blame you because this was when Bitcoin hasn't get much attention.
