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.
If me as long bitcoin is still have it's community, and a lot of people start to adopt, learn and using it no matter what is their purpose. I think already be ok for me because demands will still created and bitcoin will have it's value.
