They want the money of some people especially those beginners.
Especially those new ICO, out of 10 projects , maybe there are only 2 projects are legit. Maybe we can say they are legit but it will slowly disappear and abandon their project. This is normal especially in the world or cryptocurrency.
Not even 2 of 10 projects are legit, in my case none of them are legit for now. I had followed a few projects these months and all of them were a scam. A scam project will always tell us about something good while they have not done it yet, even the latest ICO project that I have been following all this time posted about their activity on some event ended up scammed me.
They were trying to get money but because the demand is significantly low, they are not able to get what they wanted and then create another project to get money from it. The cycle moves like this multiple times.
