probably because its garbage. It doesnt actually use the space for anything useful, its just a another wasteful pow, wasting hdd space. you cant actually store data on burst, it has the same "waste" problem as normal pow, just instead of energy its wasting hdd space (and some energy)... coins like storj, sia, filecoin, swarm and whatever this guys cooking up actually use the drive space for something useful instead of wasting it.

burst is really really dumb if you actually think about it for a while, and its a complete clustefuck of infighting, ddos and botnets... just ugh, terrible, just terrible... wasting all those harddrives that could be used to store useful data on what? guessing random numbers? thats the exact fukin problem these hdd farming coins are trying to solve: creating a pow that actually does something useful beside provide security: using harddrive space to create a decentralized cloud and incentivize people with crypto to provide their space to the network.

the moment any of these coins can generate more money per TB burst will disintegrate like the shitcoin it is.
