I don't know about rich in 2018, but if you are willing to invest in noteworthy projects then you will be assured returns as they are built and they grow. Even though ICOs are tricky to predict, if you are willing to invest long-term (1.5 yrs) then placing your trust in solid projects like Rentberry and even the upcoming Arcblock can have great returns in the long run.
Arcblock? haha. I don't trust this one. It's only HYPE project. I don't trust them but I hope all investors will get profit from it.
A lot of sketchy stuff it sounds like surrounding it.
Rentberry is OK
I agree with you on this one. Just take a look at this interview with the Arcblock CEO with Ian, this guy is very sketchy I don't trust him at all.
