there are only 890 188 DRPU , but when you exchange your DRPS to DRPU you will get the same amount off DRPU acournding to the price of DRPU and DRPS/DRP. But when the 890 188 are clear and all exchanged then remaining DPRS will counting to be as DPRS. So this will make the DRPU rise in value and the DRPS will have lower supply of 890 188. So all in all , DRPU will go up in price and the DRPS to (but in much smaller extend doe the supply of DRPS is only going down with 890 188 DRPS. But the DRPU will go up in price much higher do its only 890 188 and the DPRS money will come in to the DPRU market. So all in all DPRU is the only coin you should invest in , in my opinon. Happy trading!
