I don't think any of them could compete with Ethereum, especially with DEFI hype , lost of them used Ethereum blockchain and it gathered volume and reputation for ETH , and if ETH 2 , runs these days, I don't think any coin could compete with it for a long time .
ETH already have good commuties behind and with ETH 2.0 it will add more support from new and old investors, it would be tough to any
new projects or even those old ones that coexist with ETH, we can't tell as we are inside crypto where anything can happened but so far
becoming next ETH needs to have lots of support to keep the postion.
