With the current deep fall in the price of bitcoins, as well as the entire cryptocurrency market, which continues throughout the current year, I am not sure that Tesla's sale of 75 percent of its bitcoins was a good decision. Bitcoin is now showing its growth again and may soon approach the selling price of these bitcoins at $29,000. But nevertheless, Tesla still makes a good profit from buying and selling bitcoins. Moreover, Elon Musk does not rule out investing in bitcoin again in the future.
