If Dash achieves a small market niche with the Dash platform, it could gain some traction, and if BTC returns to highs in the next Bull run, maybe we can hover around $250 and try to stabilize around that area.
According to free market economics it should stabilise at masternode operating costs + a risk premium on the collateral.
Masternode operating costs are around $30 a month which would value Dash at around $5 (based on rewards of 6 Dash per month).
Add a $25 per month risk premium (pretty generous at 600% of operating costs) and you get the stable long term price = $30.
Certainly right now it would be a reasonable price. $30 for each Dash and based on what you can offer today would be acceptable.
But let's think that the platform offers some more incentives in the style of ETH and its chain of smart contracts. It could give us an improvement in its fundamentals, and gain market capitalization.
I remember at least three years ago I said that it would be nice if a part of the budget was spent on buying gold, and that each Dash had a small part of gold that would make whatever happened happen, a Dash would always be worth something... obviously it was preferred pay big salaries to Dash visionaries, rather than use a small portion of the budget to deliver core value to the Dash chain.
All the best
