When SCD is initially issued the dividend pool will be 20%. It's important to be clear that SCD will not be a right, but rather something we issue to those that meet the necessary compliance requirements, since it will effectively be a crypto-security...

The reward pool for SHP tokens & sentiment participators, will be variable between 0-20%, depending on the other factors that contribute to the reward formula.

If you want more information about sentiment rewards I would refer you to section 6 of the whitepaper.

Thanks!
