loanbase also collects info from social sites, but it is not mandatory. So loanbase would be the better choice.
I see that btcjam only accepts payments in BTC, what about loanbase? Is it BTC payment only?
The loan is handed out in bitcoin, yes. But you can choose to calculate in USD, which means if you request 500$ at a bitcoin price of 500$ you will get 1 Bitcoin. And when you have to repay the loan, but the btc price is 2000$, you only have to repay 0.25 BTC plus interest.
I will be mad if after I sent all these documents in, that they want more information to continue for a loan.
For loanbase you just need the normal verification stuff and an income proof.
Social accounts and so on are not mandatory, but could give you a better rating. (I added some accounts, but did not get a better rating... so I do not advice to add anything, cause there is no guarantee do get a better rating.
And also based on your rating, you have a fixed lending rate.
So if your Rating is C4, you have a "fixed rate" of 23.31% . This is the interest you have to pay regardless of the timeframe. so if you borrow only for one month, you have a high interst per year. While if you borrow for 9 months, your interest per year is lower (with 9 months it is something around 30% per year).
