Frequently asked questions

What is opportunity cost in bitcoin terms?

The bitcoin you did not buy with money you spent elsewhere. The tool converts a purchase into sats at today’s price and projects scenario values for future years.

What is a sat?

The smallest unit of bitcoin: 1 BTC = 100,000,000 satoshis. Thinking in sats makes small amounts meaningful.

Should I never spend money then?

Of course not — this is a perspective tool, not advice. It simply makes the trade-off visible so your choices are conscious.
