Well, sincerely, I don't know, I even wonder how this people come up with this type of data, how is the fear and greed thing calculated? Cus right now, it's the only thing on my mind, do they go about asking traders whether their reason for buying bitcoin was because of greed and their reason for selling was out of fear,??
This things to me means absolutely nothing but I guess it's because am not a trader, may be traders really make us of this data to help them make some important decisions during trading.
