Yes it should be so, but remember that stupid lending systems are crashed down all today because the fall of the market.

Etherbanking could easily stop to pay daily interest and close the site, like the other lending system.

Now they are paying ONLY by their proprietary coin, EBC. And for now it's not convenient to sell them any day to have some $.

But try to calculate what will happen if this plan have success, and all your daily interest are paid by Ebc at 15$ rate. Try to calculate what it will happen to your wallet when this coin value will be 30$?

You will have gained the double of what you was gaining before, with Btc or Eth daily payment, right?
