The minimum bid size is €5. The bid size is doubled after each time your portfolio increases by 200 loans. Or you can use our "Bid Size" feature that enables to set your own bid size to any amount as long as it is divisible by 5. 200 is an important number because analysis of the investors’ portfolios shows that the risks of a portfolio substantially decrease after reaching 200 unique loans. This means that your portfolio return becomes stable and on 95% of cases is above 10% of return. Therefore increasing the size of the investments after each 200 new loans allows you to lend your money faster without increasing risks.
