If they decided not to pay you money no one their not will force!! Sadly of course, but it is a fact. There are projects that pay, but still they turn out to be scammers or unsuccessful ICO. Be sure to report this Scam to the appropriate topic, the guys on the first page gave links to these boards.
The saddest thing is that people like to risk things a lot, even when you report the project today, we still have so many people that would not listen and would still risk investing in such projects, and aside that, we still have lots of people that are not reading news, so they don’t even have a clue to what is happening, all they just do is take the whitepaper, study it and invest their money based on how promising the white paper looks.
So this scam of a thing will be an ongoing thing and the solution is juts in our hands, we need to stop investing in project that we have no deeper knowledge about, any project that looks promising through their whitepapers must still be vigorously researched.
