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.
I know about that, i will try to sell you if people and so many bitcoin supporters are aware about that. Have you ever heard the second layer solution called RSK and lightning?
These second layers platforms were dedicating to fix the innovation problems that faced by bitcoin. I know that so many people were also saying the same thing like you since bitcoin has limitation caused by it was not programmed or adopting the smartcontract. I should remind you that ethereum was using the bitcoin code to create the smartcontract.
These second layer solution makes you able to issue your token like ethereum. Since bitcoin native chain will not able to adopt the smartcontract and bitcoin community was creating the second layer solution for bitcoin to fix the innovation problem that faced by bitcoin.
