Bitcoin ≈ Mycelium 🍄⚡️ Both grow from the edges, not from the center.
Both are decentralized networks that strengthen as they spread.
Both are resilient, adapting to pressure instead of collapsing.
Both connect individuals into something far bigger than the sum of their parts. Mycelium transforms forests.
Bitcoin transforms societies. When energy, value, and information can flow freely without a central controller, new ecosystems emerge — more open, more antifragile, more human. #bitcoin #mycelium #decentralized #freedomtech #antifragile #nostr #plebs #fixthemoneyfixtheworld
