John, I really appreciate your DD. Banks are capitalists, if they can make money on a product, they will do it.
The micro lending biz does not lend itself to a profitable line of biz, given their administrative overhead. It takes just as much work/expense to loan $5 million as it is $500.
JMO, a bank will invest in a micro lender, given the high returns, but only after seeing a historical default record. One default wipes out the return of 5-10 repaid loans.
KPAY needs to prove it can be successful with a seasoned portfolio before a bank will step in.
