IPO - Plenti Group Limited, page-275

The monthly market is not that dissimilar to how a ponzi scheme works, existing monthly investors are paid out (mostly with the exception of the 1/36 loan repayments)by new investors coming into the market.
If what happens in Mar/Apr happens again there will be fewer & possibly no new lenders to repay existing lenders. Lenders were only saved by the massive government intervention in the economy which is about to start to unwind.
The only reason they currently have a strong monthly lending market is because of the rate which is misrepresentating what the product actually is to the uneducated.
If you don't understand the risk why wouldn't you take a rate 6 times that offered by your bank?

I'm not sure if it's happened to you but a number of my 5 year loans have had significant early repayments, with the capped lending rates that will only continue if existing borrowers can refinance.
