for me if that times happened 20%  adays bitcoin will fall . I think i will decide to sell early to protect my earnings. Lol and wait until bitcoin value became cheap then buy again and wait for the chance when bitcoin increase again . But its normal that bitcoin is decreasing cause its part of its volaitility but 20% aday it will decrease? Will  for me its not good how we become profitable if bitcoin still decreasing day by day. ?
