Important note here: If you're not a trader and are simply accumulating spot, then you should only be investing what you can afford to lose and should not be worrying about short term drawdown while we are 90% from the highs. Setting stops at these levels is for those who are actively trading. A non-trader trying to actively manage his position while we are down 90% from the highs usually ends in him getting shaken out down here before the real rally begins. Instead, DCA in and don't go heavier than you're comfortable with so you don't have to worry about needing a SL.
