Bitcoin isn't a gamble. It's a retirement plan.
Most retirement plans assume you put money in a system that quietly erodes your purchasing power for 30 years. Inflation eats your savings. Interest rates lag behind. You end up needing more than you planned.
Bitcoin is different. Its supply is fixed at 21 million. Its price growth follows a mathematical power law — the same pattern that describes how cities, the internet, and other networks have grown. It hasn't broken that model in 15 years.
The question isn't whether to own Bitcoin. It's how much you need, and how to stack it systematically. That's exactly what this calculator answers.
This calculator uses the Bitcoin power law model — a mathematical relationship between Bitcoin's price and time that has held since 2009. The model projects a price range across three scenarios so you can plan with confidence.
