Knowing when to exit... it's not when you think it is. It's usually hodling for longer than you imagined, but also selling when you never thought you would sell. There are always shiny things somewhere else trying to get our eyes off what is the good investment, has been a good investment and will likely continue to be a good investment. "But this token made some peopole 500% gains!" Nope. If we sell the trustworthy investment, to buy the shiny "500% gains" we would ride it all the way down to oblivion!
