Last November, Grand and Bruno deducted a percentage of bitcoins from Michael’s account for the work they did, then gave him the password to access the rest. The bitcoin was worth $38,000 per coin at the time. Michael waited until it rose to $62,000 per coin and sold some of it. He now has 30 BTC, now worth $3 million, and is waiting for the value to rise to $100,000 per coin. Michael says he was lucky that he lost the password years ago because, otherwise, he would have sold off the bitcoin when it was worth $40,000 a coin and missed out on a greater fortune. “That I lost the password was financially a good thing.”
