I was under the impression that only shitcoins did something like burning their supply, after all it is a measure that it is done to artificially raise the price by trying to manipulate one side of the equation of the supply and the demand.

They do not seem to realize that they do not need to do anything remotely like this if they just created some kind of service that people actually wanted to use and they needed their coin for it, so to me this is nothing more but an attempt at manipulating the perception of people and as such you should stay away from such coins.
