I once met a millionaire on my travels who sold his house and moved into a camperhome with his family. I met him just as bitcoin was at 17,000. We were talking about investments - rich guy and hippie. I, as a hippie, told him that I was now putting everything into bitcoin and he told me that he wouldn't do that, that he was paying a professional advisor to invest, who advised him to wait - bitcoin would still go down to 12000. He said he won't invest in bitcoin until then. It's a good thing I don't pay any professionals...
