A $300,000 loan at 6.5% costs $382,633 in interest over 30 years. One extra rule changes that: interest is only ever charged on what you still owe.

A Bellagio probability analyst just burned 37 years of loyalty to the ground - and took MGM's entire mathematical playbook with him.
Fired on a Tuesday over a payroll glitch. By Wednesday he had written the document that exposes how casinos collect $4,000,000 on a single Saturday night without ever risking a dollar.
This is his revenge.
$340,000/year. The man MGM called when the numbers stopped making sense. 37 years protecting this system. 48 hours destroying it.
MGM's lawyers sent three takedown notices. It's still up.
Here's the math he kept secret for nearly four decades.
Every game runs on negative expected value for the player. Always. By design.
European roulette: 2.7% house edge. 200 tables. 500 spins. $50 average bet. One Saturday night: $1,350,000. From roulette alone.
Slot machines: 5-15% house edge. 800 machines running 10 hours: $12,000,000-$36,000,000 extracted in a single night. The machines never close. The math never stops.
The jackpot illusion he personally designed signage around. A $2 lottery ticket: expected value -$1.40. The $10,000,000 prize doesn't move that number by a cent. It just makes people buy more tickets.
He knew. The casino knew. Nobody told the players.
$10 bet. 2.7% edge. 1,000 spins. Expected loss: $270. Not estimated. Mathematically guaranteed.
He watched this happen every night for 37 years. Smiled at guests walking through the door.
Until Tuesday.
Watch the moment [Fig. 2 - Cumulative Profit over 10,000 Bets]
Best case: flat. Expected: -$2,700. Worst case: -$6,000.
Zero scenarios end positive.
The chart every casino GM has memorized - and every player at the table has never seen.
