About SatSites

Updated October 4, 2026

SatSites is the front door to three free sites about Bitcoin. DG Tulman runs SatSites and all three.

Why SatSites exists

Bitcoin is easier to follow in three parts: how it works, what the numbers show, and what to do next. Each part has a site of its own, so each site can keep to one job.

SatSites is where the three meet. It explains how they fit together and helps you choose where to begin.

Who it is for

SatSites is for anyone who is new to Bitcoin and wants a plain place to start. It is also for a reader who knows one of the three sites and wants to find the other two.

The three sites

Think of SatSites as the visitor center: Facts explains, Stats illustrates, and Acts guides the next step. Start here if you are new.

How the pages are made

The figures come from public sources. Each chart names its source and the date of its data, and a program redraws the charts every morning.

The short lines in quotation marks that go with a picture or a chart are commentary. The figures, the sources, and the explanations are in the text around them.

AI tools help draft and check the pages. DG Tulman decides what is published and answers for it.

Corrections

If a figure or a sentence looks wrong, write to [email protected]. Say which page it is on and what the source shows.

How the sites are meant to pay their way

There is no advertising. The sites are meant to pay for themselves through affiliate links. Where a page carries one, the page says so, and the affiliate disclosure explains how those links work.
