Just checked DMD diamond and that coin doesn't look healthy at all. 24h trade is only 160k which is below 10k coins. So 24h trade is less than one masternode! Seem's like really unstable coin which could be below 1$ tomorrow. Selling masternode would dump the coin down heavily. put that in perspective it would be same as dumping 726854 bitcoins to market. Although with bitcoin there would be actually buyers in the market.
Yes, DMD trade volume is low (which is why the Dev is actually urging people to sell some, which in itself is a pretty strong signal), but my point is DMD is more than four years old and had slow steady growth for most of the time, so quite the opposite of an unstable coin. The Masternode number has also been growing since the introduction of Masternodes, so at least some people seem to be willing to invest quite a lot.
I also disagree that investing in a MN and selling a MN for the same price is the same, if you hold a MN for a long time you know rewards work, are stable etc., and you are also psychologically more invested in the coin, but at the end of the day everyone has their own investment strategy...
Personally I don't see any reason to invest coins like DMD.. low volume which is easy to manipulate. Price that has fixed and would dump if people starts to sell. Probably all the buyers are same people that already have masternode or close to get one or second one. Buying those few extra coins from market etc. There are so many better coins! Example like Phore.
I agree that holdin MN long time would make you psychologically invest. I don't have argue that MN are bad or anything. I think MN's are great and they might be the future of the coins. People are more invest if they have masternodes. Problem is the masternode price. It would break or make the coin. If the price is too cheap it could just lead to the point where 99% of the coins are locked and coin is basically useless. If the price is too high it would lead to price cap and low master node count. I feel that 10k phore is just too expensive and it makes it really hard to get 1b market cap. if we get there, then we have 1 million masternodes. It would be just absurd to think that people would keep them. (unless it takes like 5 years to get there so every masternode have time to generates 2x original amount). Sure you have steady income, but investing a million in this bull market could get you second million in a month! Also you probably wan't to take some of your money out! like buying a house or something.
