Agreed, that are some strategy to those scam ICO. They can be popular in the public or have a nice road map, whitepaper. But in the end it all a scam. We better aware now and be picky to choose an ICO to avoid getting scam.
Yeah and if you're not picky with icos, mote likely that not you'll end up as victim and would likely lose money due to scams. You have to be extra picky and meticulate when studying icos because a lot of there are far from what they seem to be.
