Publicity stunt for both Bitcoin and Tesla. Those Bitcoins were probably exchanged for USD within minutes. USD > Bitcoin > Tesla > Bitcoin > USD
What! Doesn't that guy know that Bitcoin is in a bubble? ( Greenspan, who has spent his life studying bubbles, said so) Wait until he gets in the car one day and the whole thing falls apart on him. Then he will be sorry. There will be a crash and it will all end badly!
Similar thing happened half year ago, I think a Porsche or some muscle car was bought for BTC for the first time, the value was around 40K. Now if the seller kept the coins the price increased like 8-10 times, so it was the buyer who made the worse deal...
