Bitcoin and Ethereum are two different crypto which tops in their own way and I think it doesn't make any logic or sense trying to find out better amongst them. Ethereum has its own sphere of influence wherein it topples Bitcoin and Bitcoin remains as undisputed king of crypto for its vast influence over the market.
People will select either Bitcoin or Ethereum as thier preferred coin based on their usage and domain.
Gold words. These coins really make a great contribution to the development and improvement of the crypto market. Bitcoin acts more as a reliable asset and an asset for long-term storage of earned money. Ethereum is primarily for investing in new coins. It allows new projects to create their own tokens without any special difficulties and attract investments for their development. Ethereum is more risky for investing than Bitcoin.
