Their are better projects to put your money in. No one will tell you them because they are waiting for the projects to be released. Once they are released they will start promoting them like crazy and by that time it is too late to make big profits. That's all I can say.
NXTL also seems like it has a probable huge number of sock puppets, something which people raised issue over but nothing was really done about it,
Are there better projects? Honestly hard to say, I read the ANN section all the time and don't really see any. Most of the alts coming out are still first generation $hitclones
