The Bloomberg Galaxy Crypto Index tracks digital currencies up 66% this year, tripling gold's gains and outstripping stocks, bonds and other commodities. The main reason for this increase is the skyrocketing Ethereum price. This is the digital currency that accounts for more than 30% of the Bloomberg Galaxy Crypto index. Currently each dong is priced at 341 USD, up 163% from the beginning of the year. Bitcoin, the world's most popular digital currency, is up 46% this year, currently trading at around $ 10,491 a coin.
