Elon's framing: future money = mass + energy. For us, that screams Bitcoin. But he didn't say that, so is there anything closer? Honestly... not really. It's not like we're heading toward a barter economy. You need something already recognized as a store of energy and value. And once you're off-world, central banks don't matter, there's no Fed on Mars. What you actually need is a decentralized ledger to transfer and store value. Could be Bitcoin. Could be something else. Who knows? But my money is literally on Bitcoin. That's my bet.(Lark Davis)
