In conclusion and in regards to DASH its obvious that there is a good mix of all these features. DASH does not fall behind in any of the requirements. But it has a big potential of gaining a very big user base with instant transactions and micro payments. Governance and masternodes may have catapulted its value up to this point. But the future is mass adoption where governance and blockchain funded projects will help to drive it further.
One more comment on the "feedbak loop": The number of masternodes can be inspected here: http://188.8.131.52/~pub/Dash/Dash_Info.html
No masternode owner is bound to hold the collateral longer than he wants. It can be sold as soon as required. The assumption that at some point suddenly a large number will be liquidated is simply wrong. And 1000 DASH for a couple of nodes is not a big factor. In Bitcoin thousands of cold wallets exist with bigger collateral and higher volatility in the Bitcoin market. The bigger question is if there is a better medium to long term investment. But that is a point that hits all altcoins as we can see every day - Bitcoin goes up then altcoins go down and vice versa.
Dash HAD the best mix of features. They will soon be passed by. I will just leave the coins out so it doesn't sound like I am trying push users away from Dash.
- One coin has instant locked transaction in .4 seconds that are respendable in 1 minute. (far cry from 1 second and respendable in 15 minutes)
- One coin has mixing that takes about 45 minutes. (far cry from the 2 days it takes Dash)
- Other coins mix when they spend so no wait at all.
- One coin has a dual address system so one address is always in a private/mixed network and the other is public. Sending private to private is always fungible and anonymous.
- One coin has a variable block size
- A few coins have a governance system and more will be adding it.
- 2 coins have the magic API wallet system. One is already testing an API wallet.
- One coin has a separate backed and lightweight frontend with all the user options.
- Lightning and/or Thunder could actually work.
- Many coins have wallets with built in market places, coin loaning options, exchanges inside wallet, 2nd layer assets,
There are a lot of good technologies out there. One coin in particular has many of these features and is not wasting time talking about how to spend budget money on advertising. lawyers, or conferences. They are just writing code and give solid weekly updates.
I think the feedback loop with masternodes will not look like a drop in masternodes. There are are more and more coins put into Dash every day from block rewards. So the number of masternodes will keep growing. The problem is that the value of masternodes will fall. Once enough of a drop happens, the budgets will get smaller, and that further causes a collapse. It could be saved, but the mistakes I have seen make a drop likely.
