Musk's recent promotion of dogecoin on Twitter has also lifted the price of that cryptocurrency.
Last month, Tesla revealed it had purchased $1.5 billion of bitcoin and would soon accept it as a form of payment for cars, sending the price of the world's most popular cryptocurrency soaring.
Bitcoin hit new highs of near $62,000 over the weekend but retreated about 5% early in the European day on Monday.
In another statement, Tesla said President of Automotive Jerome Guillen had moved to the role of President for Tesla Heavy Trucking, to lead Tesla's entry into “the critical heavy trucks market for the first time."
Tesla said in January that it will begin deliveries of its long-delayed Tesla Semi trucks in 2021.
