No altcoin can be compared to Bitcoin and Bitcoin will forever be a king in Crypto. But if you want to overthrow Bitcoin, only ETH can do it. Because ETH is also developing strongly and is trending up like Bitcoin before
I agree, although Bitcoin is the "King" of all Cryptos, unless we see Bitcoin making some amendments to its protocol we may see more innovative alt coins rising up to take its place. Ethereum is one of them. Although it has much catching up to do in the markets I think its a possibility. China recently ranked Cryptocurrencies and Bitcoin was not in the Top 10. The index is based on three criteria: technology, application, and innovation. Ethereum came first, while Bitcoin was only 13th.
