masternode system is well known scam method. pirl will disappear like all the dash clones do when enough masternodes run on the network. I can't imagine what idiot would put his 20000$ into masternode of coin whose team doesn't even show up.
I ask you not to compare code of Pirl and regular clones of Dash, everything is much more complicated, PIRL is note one of those hype high roi coins.
