Drip Network - Is it interest?

Please could you advise on the Crypto Project - Drip Network.

I have read the white paper and it states that rewards are sent back as dividends, which is fine. However, they have a ‘hydrate’ option which basically allows you to compound these rewards so that they are added to your initial investment and so forth. I would like to know if this is classed as interest?

Thank you

I’m also interested in Drip but I’m not sure if there is anyone here answering and addressing the forum questions.
