Of course, banks give interest commensurate with currency inflation. In this case, 11% per month is the future inflation of this coin. This is a very big inflation. It would be nice if the interest rate was reduced; this will save the price of the coin in the future.
If the market for this project opens up and attracts the necessary number of interested people, then this inflation will not be so. Demand for a coin will block these 11% of inflation.
