From the Wall Street Journal:
The price of bitcoin rose above $9,000, extending a rebound that has made cryptocurrencies far outperform traditional asset classes this year.
Bitcoin on Monday reached $9,396.33, a 13-month high, according to CoinDesk, a research site. While stocks, bonds, gold and oil are all up this year, bitcoin's rally trounces them all. Prices for bitcoin and rival digital currencies collapsed last year.
Investors cite more institutional support for cryptocurrencies, escalating U.S.-China trade turmoil and Facebook's planned digital coin as catalysts for the latest move higher.
