I'd be looking at Payfair as a short/Midterm hold. There is a lot of uncertainty in regards to the project being very similar to Confido, and people are worried it might end up with the same outcome.
The other one is Mywish. Currently only on ED, so any news of a new exchange will likely make it take off.
In my opinion, if PFR fails it will be because on incompetence rather than a flat out scam. The developers have provided time stamped pictures of themselves to prove that their identities are real and that they are not going to disappear. They are struggling with brand image and marketing but a lot of us investors are helping with that by pesting them on their tele. Their changed their logo because of it. It's not much improved and the white paper has is now error free thanks to us. But yeah it's pretty bad these problems exist at all. At least they have a working demo.
