The loan I'm thinking of is for 2 months, and I will be able to pay back at least 0.75 btc.
And I was thinking of exchanging everything I have into ethereum or litecoin, so that's good.
Also, be careful getting this loan with any user. Someone could pretend to be willing to give you the loan just to run away with your 110% collateral (i.e 0.66 BTC worth of ETH) right away.
