So lets say there are 1000 nodes and I have I secure node. I will receive 7,560 zen cash per month that is calculated in today prices = 160 $, if the number of node rise to 2000 i will receive 3,78 zen per node. Now to receive equal amount of USD(160) as previous month the zen price would have to be 42 $ which is double or even more if i want to receive more.

Now it that happens zencash will probably get in top 20 or top 30 on cryptocurrency market cap. Is this realistic to happen.

Or better question yet do you have any idea or prediction how much secure nodes will there be when they will be put in action?
