We should not compare Bitcoin and Ethereum. They have different roles in crypto and in real life, so let them be what they be! Bitcoin is the king and backbone of crypto, while Ethereum is a backbone of crowdsale in the past, and of smart contracts. As we all have see, there are so many coins, altcoins, forked from bitcoin, but nothing can replace bitcoin, and there are and will be more smart-contract-provided altcoins, but they won't be able to replace Ethereum.
in any case, Each of us understands that it is the ethereum that has many more functions, due to which it is ether that is one of the most important coin and platform for the entire cryptocurrency market. But I also agree that Bitcoin and ethereum cannot be compared, Although if Bitcoin is used not only for la investment, to earn big money, but also for real transactions of big finances, all the same, users will not like the long transaction period and a great price.
