Fans of meme cryptocurrency Dogecoin rejoiced on Thursday after it was referenced by Elon Musk, but the billionaire CEO caused markets to trend in a different direction on Friday by changing his Twitter bio to promote bitcoin.

The change by Musk was enough to cause bitcoin's price to surge by up to 20 percent, CNBC reported as real-time price tracking data from CoinMarketCap showed the value spiked from around $32,000 to more than $37,000 in a matter of hours.
