It's pure waste. You fill your disks with random data in a very computationally heavy process, and then wait for your "number" to be called on the network, for which you get a reward(which admittedly can be/should be done on a thin client like a raspberry pi, as their docs recommend). The more storage you invest, the more numbers you have, it's analogous to bingo in a way.
