Did you actually read anything I wrote in this post ?

Its the FIAT gain that's relevant, not the Dash. Who cares that you start the year with 1000 Dash and end it with 1060 if your entire holding didn't accrue value over that period ? From an investor's perspective, the ROI is measured in $USD, not Dash. So you must take capital gain/loss on the collateral into account. By those measurements you posted, investing in bitcoin would have yielded no ROI even if you held from $100 to $20k.

The problem we have in Dash is sustaining high prices because we don't benefit from the increased scarcity that high prices bring to a fully mined coin. As our price increases, the new supply is delivered to holders with an inbuilt capital gain. That puts enormous pressure on markets which is asymmetric. Masternode rewards disproportionately pulling the roof down on marketcap with every $100 of price increase because they're at a far higher gain than anyone else and therefore have more to lose by holding their rewards.

Mining rewards do not have this corrosive effect. They are spent on attracting more competition for the supply, not wasted like masternode rewards are. That targets capital gain growth.
