Bitcoin dropping + Lack of a release + FUD.
Check out XSPEC's 7-day graph compared to other popular coins, the graph is virtually the same:
https://ibb.co/nNtTVHCould you tell me which of those is Monero vs Spectrecoin vs Bitcoin? Probably not and even on longer time-frame graphs you can see that XSPEC follows a similar height and drop as many other altcoins since most alts are so grounded in Bitcoin. Basically, once Bitcoin goes back up, and a new XSPEC release drops relieving some doubt, it will likely return to the $3 it was hovering at before the Bitcoin fall. XSPEC is high risk, high reward. Do your research on all the features and FUD before you invest.
But what do I know, I'm just your typical XSPEC shill ¯\_(ツ)_/¯
