Guys! I'm a lazy beginner in this currency

. If it is not difficult to explain in the difference between the DRP and the DRPU? Thx!
DRP = old token. It can be converted to the new tokens DRPS and DRPU.
DRPS = Security token (voting, dividends)
DRPU = Utility token (double voting power, higher ICO discount. No dividends)
Thanks.
