I know TALK, it is a reward token for users of Yobit's crypto forum, Crypto-Talk. However, TALK token has very little use value, almost none, so its price drops from 10 RUB to 0.16 RUB in a short time because the number of TALK continuously increasing from the activities of members. forums & 1% profit per day from InvestBox.
Yobit need to have more solutions when implementing a plan to create a token.
