Ponzi Schemes and Banks
An idea isn't necessarily correct.
Ponzi scheme: an investment fraud that collects funds from new investors to pay returns to earlier investors.
The investment plan itself generates little or no revenue. When a large number of investors cash out their gains or when new investors fail to come in, the scheme collapses.
In addition, it typically has the following features:
1) Promises of above-market returns;
2) Steady positive returns with no volatility;
3) Investment strategies that are difficult to understand;
4) Difficulties or inability to redeem returns.
In other words, it's like running a bank: the platform takes money from investors, lends it to borrowers, pays investors a profit rate, and charges borrowers a loan interest rate. Everyone profits from the spread.
P2P lending works like a shadow bank operating in the private lending space. The various investment schemes are simply rebranded in ways designed to evade regulation—such as framing payments as purchasing tickets or other instruments that generate equivalent assets for discounted exits.
Ideally, this system never faces a bank run. It keeps attracting new investors (insurance companies and social security funds operate on a similar model). With a massive pool of funds, the cycle can continue indefinitely.
The problems arise from regulation and profit mechanics:
1. If profits aren't generated by creating real social value, the scheme will eventually fail to meet full redemption obligations as operating costs—such as staff salaries—climb and resources are consumed. This is why deposit reserves exist: a baseline fund that must never be touched.
2. There's nothing inherently wrong with earning from interest spreads. The issue lies in the borrowers' repayment cycles and default rates. In worst-case scenarios, funds may not be collected in time to meet minimum redemption amounts, causing a cash-flow collapse and eventual failure. That's why every such scheme defines specific terms for the deposit (investment) period and the lending period—essentially arbitraging the timing gap to manage risk.
Without regulation, you have no way of knowing how long the platform intends to sustain the game. It might pull the rug the moment deposits become attractive enough. You also have no visibility into whether the platform maintains healthy collections and a sufficient pool of borrowers.
The only thing separating a bank from a scam is government oversight.
