What-if crypto calculators: useful lessons and common mistakes
Understand what-if crypto calculators, ROI, historical prices and why past returns do not predict future gains.
A what-if calculator can teach useful lessons, but it can also trick you if you read it like a promise. The point is to understand a past scenario, not to rewrite history.
What the calculator shows
It estimates how many coins a fixed amount could have bought on a past date.
Then it compares that amount with the current stored price.
The result is a historical ROI, not a forecast.
What it does not show
It does not include every exchange fee, spread, tax event or wallet transfer cost.
It does not prove that the same return can happen again.
It does not show the stress of holding through crashes, news events and long flat periods.
How to use it well
Use it to understand volatility and the power of timing.
Compare several dates, not only the best-looking one.
Ask what risks you would have faced during the holding period.
