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.
When it comes to cryptocurrencies people are more likely to talk about bitcoin, ethereum and the top 10 coins, even though many other coins in cryptocurrency also have good prospects at this time, but because the buying and selling prices of bitcoin and ethereum are promising, people focus only on the two bigger ones, even though bitcoin has a big risk in investing compared to other coins, but because many people have successfully invested in bitcoin, there are many reasons for people to talk about it.
