I stake UNIFY on raspberry PI and you get around 5 to 10% extra coins per year very good and very low coin total. Great investment in for future. UNIFY is also been around over 1 year now and never had ICO and is 100% decentralized.
This looks promising - but I only have 8 RPI available right now. How can I calculate proffits - if I have ree aletricity?
