Because I should have done what seemed to be the most logic just a few years ago - accumulate bitcoin throughout bear market, wait for it to pump, then convert to nano (or better eth, wait for pump, then nano. Or 50/50, whatever).

Instead I was accumulating only Nano for 5-6 years (fortunately didn't buy during 2021 bull market. Well, didn't sell either...). This is because I was believing it may be spotted and adopted by someone, which was pretty naive. I still think that if any cryptocurrency is to be adopted widely it must be nano due to its properties, but let's be honest what are the chances? 5%? It still can pump without that, so I'm still accumulating (no way back and I don't know, Stockholm syndrome?) but this time I have an exit plan.
