Is your friend trustworthy with his words? You know what, there are people who have been friends for a long time. But with just one occassion like related to money, they've forgotten each other. I'm telling you that not everything your friend suggests about investments, they're correct.
If you're in doubt then that's the sign and giving you a warning before you invest. That's already the hint for you. And based on what I've seen, most of the projects after the presale, they dump!
