The volume of earnbet is quite low. Today the earnbet token has marked its ATH value. In a days time there is big growth with the token. Users who have been holding earnbet for a long could've recorded their profits. It has marked an 130% growth within days time. Maybe when the gambling site gets good promotion there'll be increased usage of earnbet tokens on gambling. This could boost the price further. Right now uniswap has added it and the same seems to be the reason behind market pumping.
