Tesla’s bitcoin holdings rise to nearly $2.5 billion

Tesla’s bitcoin holdings have risen to almost $2.5 billion, the electric car-maker revealed through a new security filing published Wednesday. 

Its investment in bitcoin was worth $2.48 billion as of March 31, the company said, up from its initial investment of $1.5 billion that it disclosed in February. When the company disclosed its initial investment, it also said it planned to accept payments in bitcoin, which could have added to its holdings. Shares of Tesla were down about 1% in early trading Wednesday.
