We cannot blame him for what he already do because first of all that his money but the problem with him is that he are not patient enough to wait the bitcoin to rise up again or to increase very high before he sell their bitcoin but most of us have regrets when we sold our bitcoin at the lower value because most us didn't expect that price of the bitcoin will reach that but as of now I think it's this time the altcoins will gives us a lot of profit than the bitcoin because it's price is already high and only double the price we can hit unlike the altcoins who can reach many times but if the altcoins are potential like ethereum and ripple.
