Why blame C-CEX exchange when the person to blame is Troy Hogg? He released Dignity coin that's badly coded resulting in transaction fees being way above the norms accepted by exchanges.
Smart contracts are software. Have you ever, in your entire life, seen any piece of software not have bugs on it's initial release? Bugs happen. Bugs get fixed.
C-Cex, on the other hand, has a long and sorted history of defrauding users and extortion, continuing right up to this very day. Their record speaks for itself. I need not explain myself any further.
As for Arbitrade, I do not smite them simply because the name Troy Hogg is connected to it. We have plenty of 3rd party validation from very public and credible sources that every aspect of Arbitrade is the real deal; From the miners, to the bullion, to the board of directors. If you feel otherwise, this is a free market. Take your investment dollars and your FUD elsewhere.
Oh, and "Have a nice day!"
