Is it possible?
I read
this article about DASH which also claimed that the number of full nodes on the Bitcoin almost halved in a year. This data is really alarming.
So my question is is node incentivization for bitcoin possible and are there any incentives programs going?
No there is no direct incentive to run a node, only an indirect incentive that your Bitcoin stash will be safer if you are running a full node and helping a network.
I don't think we will have any problems concerning nodes. Even Satoshi has envisioned that almost all the people will run lots SVP clients, while only big data centers will run full nodes.
