Bitcoin is mainly an investment asset now. It is not very widely used for payment, at least in my country, it is forbidden to pay with crypto here. Also bitcoin is an indicator of crypto market mood like you said. All altcoins follow its global movements but with a bigger amplitude usually. I think that it will be adopted more and more in the future so that we will pay with it almost everywhere.
I hope like you. But I don't know the future. Look at China, the government has completely closed access to all forms of crypto-related activities. I hope it is not followed by many other countries. They fear that the crypto power they can't see will destroy China's finances. Even though I'm sure they can go hand in hand. That's one proof that power can change all forms of hope for the future.
