The stupidiest thing i did was to buy 40pcs of GTX 1060's during the time when the demand of VC risen and also the price. A few months later, the price of ETH dropped sharply and the difficulty also rises making it hard for me to get back my money soon. I have wasted $8,800 worth of money. I forced to sell all my VC and other RIG parts at a fraction of the cost. I am more than happy now making money through trading in Exchange.
