Coins have different attributes and use cases. Who is to say who can make what. The best of the niche needed will win out, just like every other sector of all industries. Ethereum has it's EVM. Monero has it's RandomX algo to prevent ASICs, and it's Ring signatures to prevent tracing. Some coins are pure Proof of Stake and try to solve scaling differently, see Algorand and Cardano. There are altcoins that are just clones, referred to generally as shitcoins.
