A year ago Michael Burry Xweeted “Sell.” To his million + followers. If they liquidated their S&P 500 holdings, they would have foregone 20% gains over the following year.

Furthermore, if I was Burry I would have Xweeted "DCA." My followers could then enjoy the benefits of DCA'ing into #Bitcoin , what with it's 100% appreciation over the upcoming year. 
Moral of the story - instead of fudging around with timing the stock market, just DCA into #Bitcoin and get on with your life!
