You have stated in your August provider update that "MYC4 should not hold more than 30 % of a provider’s total Outstanding loan balance (OLB)". I find that rule sensible as a means of reducing the risks of fraud. (I would actually argue strongly for reducing that proportion to 10-15%.)
I have now looked at the Mixmarket and seen that the loan portfolio of KEEF in 2012 was 842,542$ and it had assets of 1.2 million$. Right now (Nov 2013) KEEF has about 500.000€ (about 670.000$) in loans outstanding. Does this mean that the vast majority of KEEFs outstanding loans now come from MYC4? Or if 670,000$ is equivalent to 30% of KEEF's OLB does that mean that Keef has nearly tripled its loan balance in one year. Both trends would worry me.
