Do you know the Bitcoin Ecosystem now supports advanced smart contracts? Are you aware L2 projects (Layer 2) do not "damage or threaten" actual Bitcoins? They are adding powerful extra features in a layer on top of the actual Bitcoin blockchain.
Question: Are you aware of and/or using any of these new projects yet?
Honestly, the contracts supported on Bitcoin are limited in their use case, like using Taproot smart contracts with limited features, but when it comes to smart contract experience as we see in the ETH's ecosystem as DeFi and other Dapps, it's because of the limitations with language.
For L2 as you've said they dont damage the main chain agreed, but they are not the main chain this what we need to check.
