Ok, a less cheeky answer is that we really focus on most efficient monetization of computing resources. We come up with our own investment theses based on available digital currencies and blockchain innovations out there and then we track performance and change things on the fly in real-time to increase profitability and manage risk. However, our platform is a hybrid of blockchain technologies and a more traditional distributed computing marketplace, this way we get the best of both worlds.
Looking at the site, I don't think they mine anything yet, it looks super early. But ETH would probably be the best candidate in terms of profitability. Maybe a couple of other alt coins.
It's pretty easy to set up ETH mining yourself and pocket all the money, but that's probably not the audience this software is intended for (Windows users with access to "free" electricity).
