Smooth I don`t quote you almost never but I did some maths yesterday.
What I did is simply got the sum of last 365 days of MN earnings which brought me ~ 17,5% of ROI.
I did the maths for a nodes which were funded at the beggining of MN existence and they got ~ 22% of ROI
I agree and true is that the early nodes got a bit more, consider that there was lower security of the 1000s, as they only got paid when the coins were exposed on the network on the HOT wallet (we had an exaple people loosing their coins by not knowing "how to", but they were more centralised too IMO, after a year and a half of changing hands the coins are more decentralised and the network is healthier now.
I wish I was there mining Xcoin in early days, was only following a bit the thread but each of us had the same chances, the difference is that we choose something else instead of actual DASH.
I mined LTB and AIR and earned some btc too which is already in a MNs
Who knew about the masternode network will be created, who knew IX would be created, who knew darksend would be created and you know what, the Evolution with DAPI will be live too.
If you knew all that thing I bet you`d be buying as creazy, so would I no?
The priorities drive our lives and we choose which way to go...
Have a nice weekend guys!
Time to open a beer   or two...
