Before You Buy

Decide before the money moves

Name a coin and an amount. We fill in what we measure about it, you write the reasons only you can give, and the decision is checked against your own rules. You get one dated page to keep. We never say whether to buy.

Filled in for you

  • Supply and the next unlockHow much exists, how much is still to come, and the next date on our calendar.
  • What we have not establishedSaid out loud, from the coin’s CM Profile, never left blank.

01 How it works

The worksheet, with the facts already in

Based on two of our printable sheets, the Purchase Decision Kit and the Guardrails Pack. Both stay free.

We fill in what we measure

Supply, the next unlock, who can freeze it, and what selling it again would return at your amount. Each line is dated and links to where it comes from.

You write what only you can

Why you believe in it, what would prove you wrong, and when you would sell. Most purchases that go badly never had these written down.

Your rules check it

Your total limit, the most for any one coin, how many coins at once, and a wait before buying. We check only whether you are keeping your word.

One page to keep

The Decision Record puts our facts and your words side by side, dated. Print it, or keep it in your account with the plan.

02 Buyer's Plan

Keep every decision, and your rules

The facts and the record are free. The plan keeps them, for people who buy more than once.

  • Every decision saved, and marked as bought, passed or sold.
  • Your rules kept, and each new decision checked against what you already bought.
  • The Fair Price Check: 100 checks a day, every one saved, with a yearly total for your taxes.
  • 12 Price Records a year.

Not advice. Before You Buy never says whether to buy, never rates a coin, and never links to a place to buy one. What is kept · How every figure is made
