@Adam Back joined Yahoo Finance’s Market Catalysts this morning to break down: 🔹 Why Bitcoin’s 2025 price action looks “lackluster” on the surface 🔹 Why Bitcoin treasury companies are becoming a compelling investment theme 🔹 How today’s landscape compares to when he first got involved in 2013 A great overview of where Bitcoin stands heading into 2026.

In the 1990s, governments tried to ban strong encryption. Cypherpunks printed RSA code on t-shirts to prove a point: you can't stop math. Three decades later, Bitcoin proves they were right: you can't stop math. You can't ban freedom. When @Adam Back printed the original RSA code t-shirt in 1995, he showed that mathematical truth can't be banned. Today's limited edition version carries that spirit forward. Wear the code that challenged authority just by existing. https://store.blockstream.com/products/rsa-t-shirt-2025-limited-edition
