Had a trade set up but didn't immediately have the funds on hand, so I used Tzepu's bank to take a loan for 8750 PED. 3-4 days later, once I'd liquidated some inventory, I was able to pay off the loan. It ended up costing about 27 PED or about 0.3% of the loan. I was glad the service was available or I probably wouldn't have been able to make the trade.
Basically, I got a $875 loan for 4 days for the cost of an ATM fee ($2.70).
Would definitely recommend for instances where you need short term liquidity.
