I got in to crypto years ago, I'm still holding a bag of BTCs right now, but not that much anymore, from 100% back then, now down to 20%ish, majority of my assets right now is in altcoins. Why? Aside from the waining market dominance, there is this nagging feeling of fear that it might signifficantly drop in value.
I am little bit paranoid of holding 100% in BTC, the reason for this is because of Satoshi Nakamoto still holding 1 million BTCs. Nobody knows who this guy is, if he's going to spend all his bag, that's a sure fire way of bringing down BTC significantly.
Anyway, I'm still in to BTC, it significantly changed my life. I wish Nakamoto would publicly burn most of what it is in his bag.
