Ponzi Radar

What does 0.3% per day actually compound to?

Taken at face value and multiplied out, 0.3% per day is 198% a year. That is about 49.6x what you would get from a three-month Treasury bill that pays around 4% and a government-insured deposit around 3.5%. The arithmetic below assumes every payment arrives on time, which is the assumption that fails in practice, not the compounding.

What this rate means

A textbook scheme profile

Rates in this range do not describe investing, they describe a Ponzi structure: the payout schedule only clears while new deposits keep arriving.

Money doubles in 8 months at this rate, if it were real
$1,000 after one year $3.0K no fees, no tax, no missed payment
Payout owed on $1,000 $91.25 a month for the promise to hold, forever

The red line

A guaranteed return higher than a Treasury bill or an insured deposit cannot exist. Every dollar paid above the risk-free rate is paid for with risk, leverage, or other people's deposits. A published promise of a fixed return above the risk-free rate is the definition of a return trap.

No published entry on this register currently quotes a rate in this range. The arithmetic above still applies to any offer that does.
