Sorry, this is simply not true. Year ago, 1 NEM was at 12000 sat, now it's about 1300 satoshis. As BTC is 4-5x lower than before a year, it means ~ 40x decrease. And as we were on #4-#5 position year ago, now we're at #18 and constantly falling further. Maybe it's (the position on CMC) just means that here are more projects now, that are more interesting / overhyped / whatever ... despite of this or that, it's sad at all.
The falls in dollar valuation are extremely similar to most other alts give or take less than 5%.
The fall in CMC position is down to sexier projects with more hype.
Being non mineable and closed source turned off the two most active audiences from the start. If you remove the fake volume exchanges the volume is several hundred times lower than some other coins.
I think they have a limited window of opportunity to pull it back. It has a lot of virtues. There are going to be more projects with more visibility with more of those too.
