Wie jedes Jahr versammelt sich die Bitcoin-Community in Berlin, um den legendären „Bitcoin Pizza Day“ zu feiern. Die Transaktion von Laszlo Hanyecz gilt als eine der ersten bekannten Zahlungen mit Bitcoin für reale Güter: 10.000 Bitcoin im Austausch gegen zwei große Pizzen. Zur Feier dieses historischen Moments treffen wir uns dieses Jahr im Restaurant Viale dei Tigli. Auch dort werden Bitcoin-Zahlungen akzeptiert und natürlich gibt es Pizza. **Bitte beachtet: Jede Person bezahlt ihr Essen und ihre Getränke selbst vor Ort.** Das Ganze ist als lockeres Get-together ohne feste Agenda gedacht – einfach zusammenkommen, austauschen und gemeinsam Pizza essen. Wir freuen uns über viele Teilnehmer. Da die Plätze begrenzt sind, bitten wir um möglichst verbindliche Zusagen. Vielen Dank.

**Open Reflection Circle** is a small and intimate women’s gathering in Berlin, where we come together in a cozy café to share, reflect, and connect with one another. In this circle, a small group of around **8–10 women** gathers to spend time in meaningful conversation and reflection. We begin by introducing ourselves and gently creating a space where everyone feels comfortable and welcomed. Through guided reflection prompts, we explore our journeys, our emotions, and the experiences that shape our lives. These prompts are designed to help you open up and reflect more deeply on your thoughts, your dreams, and the challenges you may be navigating. We also include a few light and playful exercises to break the ice and help everyone feel relaxed and connected. The intention is not to create pressure to share, but to create an environment where sharing feels natural and safe. The heart behind the **Open Reflection Circle** is simple: to bring together women who can hold space for each other and remind one another that we are not alone in our journeys. This is a space where we can talk honestly about our lives — our visions, our goals, what we are building, and what sometimes holds us back from taking action. We reflect together on questions such as: Where do we want to go in life? What are we dreaming of creating? What challenges are we facing in our emotional wellbeing or personal growth? By listening to one another’s stories and perspectives, we often discover insights that we might not have seen on our own. You are encouraged to bring a **notebook and pen**, as many women like to take notes from reflections, ideas, and inspiration that arise during the conversation. Toward the end of the gathering, we close with a small and meaningful practice: exchanging short **love letters of gratitude** with each other. These simple messages help us acknowledge the presence of the women in the circle and leave the space with a feeling of appreciation, connection, and warmth. The intention of this circle is not advice or fixing each other’s problems. It is simply to **listen, reflect, learn from one another, and hold space for the beautiful complexity of each woman’s journey.**

Hey You!
On Friday I will teach you a few basic steps of shuffling. We will break down the steps, in your time, in your style.
We will explore your own flow of your body to different kinds of music and how we can use it in shuffling. I want to create a safe space for everyone who is just starting their shuffle journey or is already on the path.

Ich möchte für jede Person einen Safe-Space erschaffen, egal ob Du ganz Neu bist oder schon etwas gelernt hast.

The "classical" bookswap is simple: * We meet in a café and put the book(s) we brought down on the tables. * We go around to browse and discuss the books with one another while sipping coffee or hot chocolate, or eating cake. * We write our names down on any books we’d like to take home (post-its and pens provided). * At the end of the evening, negotiate any books that are contended and take a new-to-you book home! Books/happiness shared are books/happiness multiplied! A Bookswap is 10 times better than a Book Club because you can talk about ALL the books instead of just one! This is a great way to give your books a new home and make room for new books: that book you feel guilty for not having read even though it's been sitting on your bedside table for the last 5 years, the book you liked but didn't love, the book you loved so much you want everyone to read it, the book you somehow own three copies of, that book you absolutely hated even though everyone else loves it, and so on. Moreover, you will meet fellow readers, get a new book or two, and several book recommendations. We’ve often had readers experience books they wouldn't normally buy and enjoy it. GROUP EXPECTATIONS for PLEASANT SWAPPING * Please bring a book! It's not that you bring one you take one, but do try your best to bring something. * Books stay on the tables, open for sharing, until you are ready to leave so that everyone can have a look. We are notably not first come first serve. Please wait until you are leaving to bag the book. * If two or more people want the only copy of a book, negotiate. Maybe one of you reads it first and then gives it to the others. Or perhaps they have found another book instead. Or leave it to fate and toss a coin. The best part: now you have found somebody whose taste you can really admire. In any case, please don't walk away with a book with several names on it without letting the others know. These negotiations are fun and easy, so don't shy away from a book because there's already a name on it, and feel free to put your name on as many books as you find interesting. It's not that you bring one you take one; you may take as many as you can negotiate. * Political discussions with consent: make sure the people you are talking to would like to have a political discussion with you. * Please respect this space as first and foremost a community for connecting readers over their love of books and reading, stories, and narratives of all sorts. Please be respectful of tastes and opinions. * If something is bothering you, please reach out to the organizers, and we'll do our best to resolve it. * Lastly, don't expect your book back. It will find a new home. If you love it, let it go. Major LANGUAGES (and genres) of this meetup: English, German, French, Spanish, Italian; Fiction, Non-Fiction, Serious Reading, Light Fun, “classics", Krimis, Booker winners, Sci-Fi, Fantasy, Self-Help and more. You never know who can read what languages, and there's no accounting for taste. We are a delightful and international group of readers. We look forward to swapping with you!

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
