Yes, C-Cex has low volume of trading when it comes to Burst so when it comes to pricing you can't use it as basis. I also agree with Luxe. At the same time, in my opinion, all exchanges that support the coin are important for it shows how the coin is valued. If only one exchange site supports a coin then the coin's worth is devalued and it hardly survives without the site thus can be manipulated. More exchange sites supporting then it is worthiness.
