I dabbled in it for awhile. Was big on the Cardano train. I decided enough was enough about the third time I lost 25% of my portfolio just because of some stupid Elon Musk tweet. And that is not an exaggeration. It's literally that volatile. Controlled by the ultra wealthy (Musk, Mark Cuban is a huge Ethereum holder) and the whales who bought in early enough to have amassed obscene amounts of BTC. That, and the fact that the market NEVER closes was too much stress for me. It was nothing to go to bed up several thousand dollars, and then wake up in the red less that 6 hours later. For no reason other than a tweet.
