I made this one for a friend so I still do not have my own. But the plan is to mine Skycoin. What I like with Skycoin's storytelling is the idea of going beyond BTC and ETH regarding decentralization and mining. Because, one does not need a whole storage or facility for mining - one can do it directly from home :) https://medium.com/skycoin/what-is-a-skycoin-skyminer-f2f5a7ed9d7f
