Slipstream available to all! Please if you have a multisig that hasn't been spent from and you are trying to migrate off of Coldcard wallets, Slipstream can help add an extra layer of protection while migrating those funds. Amazing work @MARAFoundation_ and @isabelfoxenduke
🚨@MARA Slipstream is now available as a permissionless public good with no client code requirement. Please be careful and conservative with fees to avoid transactions getting stuck in the Slipstream mempool in the event that competitive rates spike. For the foreseeable future, we are not charging additional fees for this service, but users are responsible for paying appropriate Bitcoin transaction fees. Slipstream.mara.com

All bitcoin are always being saved by someone. If you are triggered by bitcoin payments, your position suggests bitcoin should only be exchanged for fiat rather than by selling goods & services. For the rest of you that run businesses, bitcoin is money. Check us out at Zaprite!

Bitcoin payments are a necessity. *You* don't need to spend your bitcoin. Those 2 statements aren't in conflict. If you have a custom site, we help simplify all your payments + our API is easy to integrate. It will take hours, not weeks. Bitcoin is money. Everything else is fiat.

This is one of the best books on bitcoin available. The original Gradually, Then Suddenly series of essays helped shape my understanding of Bitcoin. Reflecting on it now, Parker and these essays played a significant role in my decision to join Unchained in 2021. GTS the book is a more coherent and thoughtfully structured version of those essays, covering the problems with fiat currencies, bitcoin fundamentals, common misconceptions, and the case for bitcoin's inevitable success. Reading it will give you a deep appreciation of the technology, economics, and implications of a global Bitcoin standard. In a world overrun with AI-generated content it was also refreshing to see that Parker commissioned a real artist for the cover and narrated the audiobook himself. Impressive display of proof-of-work.

WOW! We just received a $15,000 bitcoin grant to our 2026 operations fund from an @unchained bitcoin DAF! The grant was smoothly processed through @ZapriteApp into our @Strike business account! If you have bitcoin sitting in a DAF and are interested in supporting the mission of k-12 bitcoin education, get in touch with the team. All 2026 bitcoin donations will be held in BTC to fuel our operations.

Five years at @unchained, what a ride! I got to create, tell stories I cared about, and work next to people who made me better at all of it. @josephkelly @dhruvbansal and so many others, a tweet doesn't cover it, but hopefully y'all know how much it means to me. More soon.

Today, you’re sending your hard-earned capital to the government. You don’t get a receipt. You don’t get a progress report. You don’t get a choice. You’re just funding a system that no longer represents you and an education model that doesn't prepare the next generation for the world we’re building. It’s time to opt out. Today we are launching the Bitcoin Scholars Fund, a new non-profit scholarship granting organization. Our mission? To redirect $21 Million from the federal government in 2027 directly into K-12 Bitcoin education. How it works: Starting in 2027, your first $1,700 ($3,400 per couple) donated to BSF is a 1:1 Federal Tax Credit thanks to the One Big Beautiful Bill Act. Net cost to you: $0. We aren't just building a non-profit; we’re architecting an innovative "Zero-Leakage" treasury powered by $STRC to ensure nearly 100% of your principal hits the classroom, not our overhead. Stop funding the legacy machine. Start funding financial education for kids. The scholarship fund goes live on January 3rd, 2027, but the "Proof of Work" starts today. Follow along as we help fix the schools by fixing the flow of capital. Fund Education. Not Wars. 👉 bitcoinscholars.org

$10,000 in a checking account in 2015. By 2025, that $10,000 had roughly $8,000 of real purchasing power. You didn’t spend it. Inflation spent it for you. A savings account doesn’t save. It’s a slow leak with a friendly name.

A client doesn’t say “your rate is too high” because they can’t afford you. They say it because you gave them room to negotiate. Here’s the shift that stops it: 🧵
