I often read crypto related news in the morning. You know what Nobel economics prize winner Robert Shiller said? He says that crypto in general is a bubble (personally I DON'T think so) and bitcoin too. But besides being a bubble, according to Shiller, it is a great social movement that has no geographical or generational borders. Also he says that it's not going to worth zero.
To my mind, in the world that is a global village now, 'social movement' worth much.
