I thought, Maybe you did not see it as the right time to invest on that low price. We should not blame ourselves for not investing early because that's how it is. Sometimes we need regret so we can really learn ...
Whom would you blame if you do not make investment when the market is low and we have seen the btc has huge potential to rise back again. And still when during this dip you do not buy it then its your own mistake that you would lose the opportunity and repent later.
