There are quite a few debates and conversations on the Dash forum about this master node situation. Today it would be a sweet thing to own a master node on Dash.
When I first heard about this, I thought I'd look to see what it takes to become a masternode. Among other things, it requires 1000 dash that you can't touch. That means $300,000 USD at today's prices.
Probably worth doing earlier, not so sure about now.
Then I thought, wow, these guys will be making a lot with all the mining coming up.
Then I realized, wait, difficulty will adjust to keep the rate of blocks about the same for them. So it'll be useful to be a masternode if dash price keeps going up. Makes me wish I knew about this when it was $8 a coin.
