okcoin start P2P lending system like bitfinex.
now borrow(demand) order is 0.1-0.01%/day, total about $0.29million.
reserve(demand) order is 0.14-0.06%/day, total about $0.87million.
lend(offer) order is 0.1-0.23%/day, total about $3million.
lender/borrower/reserver can take max 360days.
leverrage rate is 1:1-2(due to your account level)
this is partly wrong.
Okcoin offers up to 1:3 leverage.
I really think bitfinex could also start to increase the possible leverage (at least for the more liquid BTC/USD market).
This would really encourage trading volume and also have benefits for the lenders (very likely higher interest rates).
