Tesla, in a surprising market decision, announced their purchase of $1.5 billion worth in Bitcoin. And to further prove their commitment to the cryptocurrency, they’re planning to allow future customers to pay for their vehicle in Bitcoin.

The electric automaker revealed in a filing with the Securities and Exchange Commission that they have invested $1.5 billion worth of bitcoin. The explanation given was to allow “more flexibility to further diversify and maximize returns on our cash.”

They also explained that the company intends to make Bitcoin a valid form of payment on Tesla vehicles. The large investment into the currency will give the company some liquidity to work with once the option goes live.

This has brought a lot of questions up as to the real motivation for this move. Tesla CEO Elon Musk has been promoting cryptocurrencies like Bitcoin over the last few weeks. These currencies operate similar to stocks, changing in value as demand changes. As a result, his occasional mention in Bitcoin has caused the price per coin to rise each time. Tesla’s announcement did the same, causing Bitcoin prices to rise to record highs.

Musk also has a history of getting in legal trouble regarding stock manipulation, promoting or encouraging various stock trades and prices. Many see this has him doing the same thing, but with cryptocurrency, where the legal line is far more gray.

It’s a strange decision, but not something that should affect the standard consumer, unless you happen to have $70,000 worth of Bitcoin you can drop on a new car.
