Representation of the virtual currency Bitcoin is seen on a motherboard in this image illustration taken April 24, 2020. Bitcoins rally is driven partially by increased adoption by bigger institutional investors and companies and speculative need. And PayPal and BNY Mellon have actually made some moves into the space.Bitcoin believers argue that the existing rally is fueled by need from institutional investors and is different than past rallies, such as when bitcoin increased to almost $20,000 in late 2017 prior to losing about 80% of its worth the next year.Others argue that bitcoin and other cryptocurrencies have no intrinsic worth and fret that bitcoin could be one of the most significant stimulus-fueled market bubbles on record.
