Many people registered in the App, but are not receiving the free tokens because they haven't go through the Authentication process (KYC) yet.
Every user has to Authenticate in the App to start receiving the rewards. This applies as well to the users who decide to purchase the mines to get rewards from 20% per month in CYTC tokens.
The Authentication process is straightforward and normally will be activated within 1 hour from the submission.
You just need to fill name and ID, send a copy of the ID and a picture of yourself holding it.
The Authentication tab is under your profile section.
Happy earnings!
