i'm only have 1x gtx 1080ti is it worth for mining this token?
When you only have a single GPU it normally is not worth mining any token. Of course you can profit, but mostly all you're doing is burning your hardware quicker than you normally would for minimal reward. A couple of dollars profit here and there, unless you are HODLing for a big price spike, that's all is being accomplished.
As other users have suggested, RavenCoin has been something that people are getting excited about and betting their electricity bills on (to put it in your own words).
ANN section is kind of mess.. cant go thru all of this..
That is the price you are going to pay if you are interested in finding the diamond in the rough. There are new mine-able coins each and every day that pop their heads up, the trouble is the next day most of them disappear. Unless you are reading the whitepapers yourself and doing the research needed to verify what value the project has, then you are mostly just going to receive responses from users spamming whatever ANN has caught their attention for any arbitrary reason.
