There are no exact terms. If you look at the list in OP, it should give you an idea. There are reference links to all of them.
My shortest loan given was a duration of only a few hours (already repaid), longest is about a year. I'm not too focused on high interest rates, but rather if the loan is for a genuine need, and if you're trustworthy enough. Of course, "genuine need" and "trustworthy" is not black and white, so that's why I'd have to screen out potential scammers.
The longer the requested duration, the more likely it'll get denied. The larger the amount, the more likely it'll get denied. But your profile and forum activity precedes all of these.
Ok I'll make a small try:
Amount: 0.5
BTCDuration: 30 days
Interest: 5%
Amount to be repaid: 0,525
BTCPayment cycle: Weekly(0.13125*4) or Bi-weekly (0.2625 * 2). The latter suits me better, but I can sustain the first.
Purpose: Investments in trusted lending sites and/or bitcoin trading. Either here in the Italian section or on Localbitcoins as it is easier for me to move EUR instead of USD
Means to repay: I have a small SHA256 mining rig (650 GHs), serious investments in BTCJam, Bitlendingclub and Cryptostocks.
