Isn't that more like staking because the last I heard of this doge interest is that you have to stake the coin, and the amount required to stake is really much that people cannot afford that much. I have not been seeing the invest box in the Yobit for some times, now, and this is one of the thing that has been making me to check Yobit out because naturally, I would not dare to go near that exchange that contains shitcoins.

It amuses me how they are the only one that have provision for that on doge which I know completely well that Doge is not a shitcoin, they would have just done that on other exchanges, except it is a personal project that is being run by the exchange directly. They might be having little issue with the invest program and we will watch if it will be restored.
