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).
