Can't say i'm surprised. The brainless shilling that went on for quite some time probably makes that a lot of people are facing severe losses now. it might recover but i would be very carefull in buying the dip. The fact devs have not been honest about their own background, rumours about copied code, etc are major red flags for me.
Another case of dyor.
I think this is all far over-blown. First of all, SpectreCoin is a community - its survival does not hinge solely on one or two developers. Ultimately, I don't find most of the attacks that valid. Any new code being written isn't going to be stored on Github - why would they do that? When it's ready, it will be rolled out and added there.
I also wonder why people are so Hell bent on bringing it down. I don't go FUD on all the projects that I am not invested in - or don't like. My personal experience with this coin has been quite positive. The wallet and staking has been quite user friendly. Sure, it shares a lot with ShadowCash - why should this be a surprise to anyone, it's essentially a spiritual successor looking to improve on what was started. While there is always risks investing in smaller projects, I think this one will be fine (in fact, I think it will thrive) in the long run. I've been buying.
