Looking at them, it doesn't really look like an exchange that many people know about.
Just on this topic there are many people who never heard about it before and this is the first time they are hearing about it because they partnered with PSG. I would understand the regular world not hearing about an exchange and only know of PSG but even on bitcointalk if people know PSG better than coincasso exchange that kinda hurts their whole sponsorship a bit
.
In the end they have done something good and this increases the popularity of their exchange, here we are talking about them and many people visited their website as well probably, hell there is probably even more people registered here as well. I am sure they will be very happy about the results of their sponsorship.
