Why support matters
21wiki is a free, open Bitcoin education resource. It is built and maintained by Tony and a small group of contributors as part of the 21ideas project.
If the wiki has been useful to you, consider sending a few sats. It helps cover the time spent maintaining sources, improving pages, and keeping the infrastructure running.
