At a time when Bitcoin reached a staggering $ 11,900, a man a few years ago made the blunder, which today would make him a millionaire. Greg Schoen, a Twitter user, had written in his Twitter account in 2011 that he had been disappointed that he had sold 1,700 Bitcoin coins when their value was $ 0.30. "Had I kept 1,700 BTC at $ 0.06, instead of selling them for $ 0.30, they are now $ 8.00! #bitcoin, "he wrote. If he did not sell his coins then Greg would now have a fortune of $ 20,236,900.
