Ethereum, the largest altcoin, keeps setting new peaks throughout the day, logging a new all-time high of $3,293 at 5:12 p.m. UTC on the Bitstamp exchange.
At nearly $380 billion, Ether's market cap has already surpassed that of financial giant Mastercard.
Notably, the company was one of the participants in the $65 million investment round of software development firm ConsenSys that was announced last month.
Bitcoin trumped Mastercard back in November when it was trading at around $18,000. In March, the leading cryptocurrency went on to surpass the cumulative value of Mastercard and Visa after it hit $61,700.
The flagship cryptocurrency's rally has since hit the pause button, with its market share now slipping well below the pivotal 50 percent mark.
