I also believe that Vitrocoin is a scam. There are simply too many red flags to be ignored. If I were you, I'd stick to smaller, yet, more promising projects with a more reliable historical record and renown. Such are Omnitude, AgroTechFarm, Giftz, and Cointed. Check them out and let me know what you think about them.
I am quite sure you are right about Vitrocoin being a big scam. I also agree that investing in smaller projects could net you the biggest profit, but that must be done with extreme caution. I have invested in 3 of the 4 you mentioned and I am not regreting it at all. But research must be done before any investment, specially on smaller companies
