There is no information anywhere on the profitability with the master node,does it make sense to invest 20000$ in this event?
Masternodes get 1 PIRL/block, so approx 6600 PIRL a day, divided by the number of masternodes.
eg : 100 masternodes on the network = each one will get around 60 PIRL a day. Means less than a year for the ROI.
In addition, masternode will get rewards from the marketplace and payment gateway transactions once they will be released.
atm there is 18 active masternodes on the network, around 100 masternode after the beta phase (when rewards will be activated, more people will run MN I guess) seems to be a good estimation, but it's hard to plan, I may be wrong !
