Ethereum is the world's second-biggest cryptocurrency, and it's giving bitcoin a run for its money. - Ethereum once was seen as bitcoin's little brother. Now, things have changed. The ethereum cryptocurrency, known as ether, has claimed a sizable share of the crypto market. And its underlying blockchain platform is powering innovations in the space, from decentralized finance to non-fungible tokens. But technical issues with the ethereum network are proving costly, with users being forced to pay high "gas fees" to make transactions. And a flood of new tokens known as "ethereum killers" are hot on its tail. That could be about to change as ethereum moves over to a new standard which proponents say will make it run more efficiently. #CNBC #Ethereum #Crypto ----- Subscribe: http://cnb.cx/2wuoARM CNBC International TV: https://cnb.cx/2NGytpz Facebook: https://www.facebook.com/cnbcinternational Instagram: https://www.instagram.com/cnbcinternational/ Twitter: https://twitter.com/CNBCi
