Tesla, the electric car manufacturer, has reported in its latest earnings that it did not purchase or dispose of any bitcoin in the fourth quarter, similar to the previous quarter. As per the report, the value of its digital assets was $184 million, which is a decline from $218 million in the third quarter, due to the depreciation of bitcoin's price. At the end of Q3, bitcoin was trading around $20,000, and by Q4 end, it was around $16,500. The company has not made any changes to its bitcoin holdings in Q3, but in the second quarter, it had sold $936 million worth of bitcoin, which was around 75% of its total holdings, to raise cash. A conference call with analysts is scheduled for 5:30 p.m. ET (21:30 UTC).
