In future Bondora will uniformly use ‘quick funding’ loans with fixed interest rates.
Since there will be no advantage for investors to set interest rates low on their automated investment profiles any more after the change, I expect the short term effect will be that investors raise the interest rate on their profiles to the actual interest rate they want to invest at (Currently it is possible and custom to bid 6% in order to heighten chances that bids participate in quick funding loans, which then might actually close at 28%).
