Financial planning tools built on 15 years of Bitcoin price data and 14 published research papers. Every tool traces its assumptions back to a specific paper.
Bitcoin tools that do the math. Save, borrow, monitor, and retire — four calculators powered by the power law model and 100,000 Monte Carlo simulated futures. See what your savings become when you stop guessing and start stacking.
When can you stop working? A Dutch-language retirement calculator using 100,000 Monte Carlo price paths, integrated with Box 3 tax rules and AOW pension timing. Model your DCA, lump sum, or existing holdings — see survival tables showing how long your stack lasts at every exit scenario.
Lending against the power law floor’s structural ~38% annual growth — not volatile spot price. A 5 BTC portfolio generates $92K in Year 1 borrowing capacity at 26.9% LTV. The loan self-liquidates by Year 2. Stress-tested against the 2022 FTX crash: debt peaks Year 6 but never triggers liquidation. For lenders, Floor Bonds are carry trade infrastructure: 10× leverage delivers ~13% ROE on near-zero default risk.
Built on research, not marketing
Every number in every tool traces back to a specific paper with disclosed methodology, sample size, and limitations. The power law model explains 95.6% of Bitcoin’s price variance across 15 years of daily data. The floor has never been breached. But our formal verification also found three problems with the model’s secondary claims — and we published those too. Our backward-looking metrics show that even without the model, the observed data produces the same planning inputs. The tools work because the research is honest.
