I was tracking a reverse portfolio of my stock trading with a friend till I stopped a few years ago. In 2 years, I walked out slightly up. It was timing that caused the difference but the reverse one was over 300%.
"I should probably sell this and buy this" did nothing, the buy idea shoors up. It was nearly sure bet. All picks were great, all timing abysmal.
At least with butcoin, it's a "sidewinder missile" trade. Just fire and forget. Thanks for the cheap SATs!
