can it happen that they will take the money and burn the pragon coin??
can it happen that they will never be on a coin exchange??
Even if you think that they are scammers which is your choice, why would not put then coin on exchange as that would bring more money so your FUD is no logical

It could have been but, unfortunately, it's not because it's already on hitbtc and more in line.
Don't trust me? Check it yourself:
