What happening with this coin ?
Not sure, honestly this coin is ridiculously undervalued right now. The introduction of PoAS should have given a huge price jump by an order of magnitude because it is just as innovative and private as other coins like, say, Zcash. Spectrecoin is basically Monero with Proof-of-Stake instead of PoW.
I hope that some whale will recognize the value of this coin.

Probably right now the price dump is just caused by noobs who are trying to time the Bitcoin market.
Of course, since Amsterdex closed down it would be nice to have a different exchange where SPECTRE can be traded, maybe that's a hint the XSPEC team could follow.

Also when the mobile wallet gets released next year that should give another confidence boost because it is basically the implementation of the SpectreCash idea from years ago (having a coin that is as private as physical cash and can be used as a drop-in replacement by paying with your smartphone).
The devs have really got their act together and XSPEC looks great and works flawlessly

Also, ZEC is probably the worst coin ever designed ever...
Having 2 types of coins is a horrific idea that kills anon and creates endless complexity...
And Zooko is such a freak that he voluntarily involved himself in the absurd Peter Todd Sex Scandal..
Maybe XSPEC needs a good sex scandal to put it on the map

Also, "undervalued" is a relative term. Relative to what?
Similar cap as ONION, ARRR... so debatable considering the design, profile, exchanges, volume and tx/day.
And the single smartest move in crypto the last 9 months has been dumping shitcoins for BTC
