What took me ages to realise is that everyone who was educated in crypto knew it was a bubble even back when BTC was $1000. What happens when the bubble keeps bubbling and popping? Just keep riding that rollercoaster and try to hop off at the top. You don't need to belive in something, just understand that it's behaving erratically and exploit it, to like you say, other people's misfortune. Ride the mass populations consensus of the claimed inherenet value of a particular coin and if it bubbles you're onto a winner, regardless of whether it actually materialises in future.
