Wednesday Crystal City Run: 50 min
For the Wednesday run, let's meet at 1750 Crystal Dr (Entrance by Morton's Steakhouse) before walking over to the Crystal City Water Park and run on the Mt. Vernon Trail alongside the scenic Potomac River.
LOCATION: Meet at 1750 Crystal Dr (Entrance by Morton's Steakhouse). Link to location on map: http://i.imgur.com/3yN0lwN.jpg
NOTES: Photos taken during the event may end up on Instagram, Meetup, Strava and similar platforms.
Let's meet at 6:50 PM, leaving by 7:00 PM. We will do 50 minutes, so 25 minutes out and 25 minutes back. You're welcome to do more if you'd like. Just before the run we decide whether we'll go NORTH (DC) or SOUTH (Old Town) on the trail. Once we're done, we meet back up at the Crystal City Water Park area. After the run please feel free to hangout and socialize with the group or join us at National Landing Water Park for a beverage and/or food. https://g.co/kgs/AErMQZ
All paces are welcome! We run by time, not speed so bring a watch to monitor your time and turn around at the halfway time point. If you need to run/walk, that's ok! We average anywhere between 7-13 minute/per mile pace.
First Time? Start out slow to find someone around your pace. The different paces tend to automatically gather, so you won't be alone!
Metro: Crystal City on Blue/Yellow lines, 2 blocks from metro exit.
Parking: There is plenty of paid parking options (parking garages, street parking, or parking lots) in the area on Crystal Drive or Long Bridge Park.
Post-Run: A lot of times we have a little social outing after the run. You can bring a change of clothes if you'd like (though most people just go as is). We'll finish up the run, meet back at the Water Park, pick up our wallets and walk to wherever we decided to go for a beverage and/or food. If you have a suggestion for a place to check out, let us know!

Bitcoin Book Club: The Deficit Myth
Join the Bitcoin District Book Club! We meet every month to explore new and exciting rabbit holes by reading books that are popular with bitcoiners.
Join us for a deep dive into *The Deficit Myth: Modern Monetary Theory and the Birth of the People's Economy* by Stephanie Kelton. In this session, we’ll explore one of the most controversial and influential economic ideas of the past decade—and what it means for government spending, inflation, taxation, and the future of money.
Kelton challenges the conventional view that governments must balance their budgets like households. Drawing on the principles of Modern Monetary Theory (MMT), she argues that countries that issue their own currency are not constrained by tax revenue or borrowing in the same way individuals, businesses, or local governments are. Instead, the real limits on government spending are inflation and the availability of real-world resources.
We'll discuss the core claims of MMT, including whether deficits are actually harmful, why governments issue bonds, the role taxes play in the economy, and how policymakers should think about public investment. We'll also examine the major criticisms of MMT and consider how Kelton's ideas relate to Bitcoin, sound money, inflation, and fiscal policy.
Whether you view MMT as a revolutionary framework or a dangerous justification for endless money printing, *The Deficit Myth* provides one of the clearest explanations of the ideas shaping modern debates about deficits, inflation, and government spending.
For those interested in economics, monetary systems, public policy, and competing visions of how money works, this book offers a provocative challenge to many widely held assumptions.
Buy the book on [Amazon](https://a.co/d/0jgks9ZG)
**Event Notes:**
* Discussion Starters: We'll kick things off with a few key questions around deficits, inflation, government spending, and Modern Monetary Theory, but feel free to bring your own perspectives.
* Future Reads: Let us know if you have recommendations for future book club selections! We'll add them to the list posted [on our website](https://bitcoindistrict.org/bookclub).
* Afterwards: Feel free to join us at PubKey after the meeting to hang out, continue the conversation, and grab some food!

* 📍 Teaism – Penn Quarter
