It is a great tool!
Technical question 🙋
How is the level for purged transactions calculated?
Is it based on:
1) how many transactions are waiting in mempool?
2) average or another calculation of most recent fees?
3) combo of 1+2?
One of my favorite tools for getting a quick glance at what’s happening on the #bitcoin network is https://timechaincalendar.com/ created by #[2] . So much info packed into a nice mobile friendly view.
