Economically no, it has hardly been a good investment for a long-term holder.
At the protocol level, it has evolved, but it seems that not enough.
where is the problem?
The problem is exactly the same one that any asset on the planet would have if it paid weekly dividends straight out of its capital value year after year. That capital gets chronically depleted.
With 5000 hungry masternodes to feed now, doing nothing but pocketing the new supply how on earth does anyone expect this coin to do anything other than lose value ?
Any now even faster - with
Spork 21.
Right now a master node hardly contributes anything to receive 6%. Nothing apart from the invested capital, and a server.
I agree with you in part.
But remember that the most affected of all this are the nodes themselves that lose value in their investment despite receiving 6% per year.
Are masternode holders idiots?
And if tomorrow dash palttform demands more from the master nodes such as the use of a lot of memory, a specific computer with high characteristics ... a kind of "mining" based on computing power at the service of the Dash network to store data and similar things.
Would the master nodes become a kind of miners?
Would this 6% return for owning a master node make more sense to the ecosystem?
The ball is on the court, but remember that other currencies do not have master nodes and it can not be said that they have done better than us.
Let's contribute ideas, and maybe the nodes will value it in some way.
