FEAR + GREED AUG 2019 BTC has just had a good pump from $3000 to $10,000 apprpox.

I would have assumed F&G would have been more in the 60s/70s because we eventually got a drop to $6000 and back to $3000.

Why was F&G so low (fear) after a pump. It would suggest the sentiment was to buy?

I know it's not a science but just curious as to why the siganls and market sentiment offered by F&G didn't line up
