I think this is a great crypto currency investment post. As people are looking more and more toward sustainable businesses it's a good idea to look into crypto, which uses solar power to offset electricity usage. It's also a good idea to look at the complexity of the crypto's algorithm. The more complex, the more energy warranted to carry out the transactions completed on the block chain. My post THE CRYPTO KEEPER: MINE YO DAMN CRYPTO provides some info on electricity and mining. Once again, great post.
