I've never met someone who got rich owning index funds while working a 9-5

That's because:

1) You need to save for ~40 years to become financially free in the legacy financial system

2) Most people are risk averse (a job is "risk-free", a business is risky) so they just hold cash - they don't want to risk their savings on stocks

Buy Bitcoin and you'll be able to retire in 10-15 years instead of 40

Bitcoin is the best cash to ever exist

You don't have to worry about a business going bankrupt and taking you with it

You don't have to worry about a CEO making it stupid decision and ruining your future

The best part:

You get better returns than people who are taking a MUCH bigger risk than you (real estate and stock investing is basically just gambling at this point)
