Nice to see that the project is moving along!

I have 2 questions/comments:

1) Does anybody know why Zencash suddenly dropped today when the main-net is already operational (which should impact the price positively)?
2) I understand that for the network the more nodes, the better but for the node(s) owners it also means less rewards which is not that great. I understand that the goal for the Secure Node is different than a Master Node for DASH but if the incentive because really small, it is possible than people will not see any value anymore in setting up a node and so on. Thoughts?
