#2 loan (with ability of earlier repayment). BTC will be used for: 1) Renting mining rigs. 2) Invest in some cryptocoins with "Proof-of-Stake". For list and calculating ROI I use www.cryptoid.info web-service. Im also using it to calculate difference between costs of renting rigs and profitability of mining. Of course, there are some websites, such as: coinwarz.com, whatmine.com - but I prefer to calculate myself. It's more better. Thank you for Investments!
