[Date changed!] Welcome to the Berliner Bitcoin-Stammtisch, where we gather to talk about the digital currency that's worth more than gold and sometimes causes more drama than a Netflix series. Join our tribe of business beings, developers, and activists who believe that Bitcoin is the future of money, and El Salvador seems to agree! Here you can learn the ropes of Bitcoin, from buying your first fraction to safely storing your private keys. Our current hangout spot is Friedel Richter on Torstraße, because ROOM77 is closed until the last block is mined. You can pay in Bitcoin ₿ or Lightning ⚡ and enjoy awesome regional food with an international twist. So come join the fun, the food, and the revolution! We're waiting for you. 🍔🍔🍔

We improvise all the time! ​It's coming up with a story to tell someone. Making up an excuse when you are late to work. Having to do a presentation when you have lost all your notes. Improvising is also coming up with a joke or a pickup line on a date. ​Improvising can be challenging, but it can also be fun. It involves spontaneity and creativity. Whether or not you think you are good at improvising doesn't matter. You may surprise yourself. So join us for an afternoon of improv games where we certainly will have fun! ​--- ​The event will start at 14:00 and last up to 2 hours, with a 10-minute break in between. You'll find us in Tiergarten at the following spot: [https://maps.app.goo.gl/dzXw9NXMLAjBqBUE9](https://maps.app.goo.gl/dzXw9NXMLAjBqBUE9) The communication before, during, and after the event will happen in our Telegram group: [https://t.me/czc_berlin](https://t.me/czc_berlin).

This will be the first meetup of the group. A relaxed evening for people interested in bug bounty hunting, web security, AppSec and vulnerability research. The main goal is to meet like-minded people, talk about bugs, tools, targets, methodology, reports, interesting findings and whatever else comes up around security research. Since it is the first event, we can also spend a bit of time discussing how future meetups should be structured: casual chats, hacking sessions, short talks, tool sharing, report discussions or presentations. As soon as at least **3 people join**, I will look for a suitable location. The first meetup will probably be in a **café, bar or restaurant**. If there is enough interest in presentations, I can also look into booking a room with a **TV or projector** for future events. No preparation needed. Please keep everything legal and authorized.

An invitation to soften, slow down, and listen within. Through grounding movements, mindful breathing and guided reflection, this class creates space to reconnect with your body and nervous system. We begin with an intentional asana practice to awaken the body and build awareness from the inside out. As the practice unfolds, mindful movement and conscious breathing will support you in tuning into your emotional and physical state with greater clarity and presence in the now. The body holds stories, sensations, and emotions while the nervous system often guides how we experience them. This class offers a gentle space to regulate, reflect, release, and reconnect. Guided reflections are woven throughout the practice to support deeper self-awareness and integration. You’re welcome to journal, simply reflect internally, or engage in whatever way feels supportive to you. Please bring a journal and pen if you’d like. https://www.eversports.de/org/activity/0374c592-0743-4067-a6bf-7f1e47b11b1c

If you were in CA for Figma Config, tell us all the lines and you can tell me how I can animate an SVG without coding it by hand, and why I’d even want to. Thanks to the team at Nationwide of supporting the group.
