This is just my personal feeling, groundless. If my idea is wrong, please correct it.
I learned about cryptocurrency only last year. I was lucky to know several senior players. I found a preference among my friends. Friends who support bitcoin will despise other coins, and he will scoff at new play items in the market. Friends who support Ethereum are very interested in new projects and will understand or participate in them. Over time, I feel that the friends who support bitcoin are conservatives. He only agrees with bitcoin; The friends who support Ethereum are energetic.
The most important reason for Ethereum's success is that Ethereum's smart contract adopts Turing complete technology, which makes the function of smart contract very powerful, and gives birth to popular application innovations such as ICO, defi, NFT, gamefi, etc.I think bitcoin has not changed and may not need to change. Bitcoin is concerned by the state, and Ethereum is a cryptocurrency that cryptocurrency players must buy.
I'm just a feeling of myself. I don't mean to offend anyone.
Etherum's innovations made it even more popular, and the Smart contracts adopted by many other blockchains gave Etherum a very positive impact. I love Ethereum as well as Bitcoin. we need to distinguish between the two, Etherum is an Altcoin as an alternative to bitcoin. Unlike the case with Bitcoin which does have a very high price and is not classified as an altcoin, so Etherum was created as an alternative to bitcoin.
