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
Well I wonder what you thought bitcoin was that you could easily forget it for so many years and only remembering it now. Fact is that either your very rich, irresponsible stupid or just lieing, cause I believe that anyone would hardly leave his bitcoin for so many years with all the news and FOMO from bull to bull and different cash range and your mind never flashed back, well it would have been eevn better you never remembered.
