I think the most optimistic outcome for Bitcoin would be to return to its roots, which is to play to the nature of bitcoin as a currency, as the opposite of global fiat currencies, coexisting with global fiat currencies and ready to replace the declining credit of fiat currencies, such as overissued US dollars.
I am optimistic with what El Salvado has done, bitcoin should be more legalized for today's modern economy and industry. Conservatisms and lax management should be replaced. Bitcoin doesn't need to change, the way it used to be.
