Isn't there a fear and greed index for crypto just like there's one for the stock market?

I have a feeling there's still nervosity and a lack of mainstream adoption in crypto. Maybe even a decrease. Bitcoin dominance is rising, not because of new money coming in but because of people selling altcoins and ICO tokens.

What does it take for crypto to become appealing to the mainstream again? I think the banks and governments getting into crypto is like your parents liking the same as music as you: it's spoiled.
