The Most Radical Thing About This Isn't the 0% Rate. It's Who's in Control.
Every so often a shift in finance shows up without a press release. No ticker to hype, no promise that a number will moon. Just a quiet change in the answer to one question: while you use your money, who is actually in control of it?
For all of consumer finance history, the honest answer was "someone else." A bank held your deposit. A broker held your assets. A lender held your collateral and set the terms. Using your wealth always meant handing it to an institution that could change its mind, and, as 2022 reminded everyone, sometimes go under and take your money with it.
Bitcoin already changed that answer for holding. You can custody serious wealth yourself, no counterparty. The quiet part now happening is that the same answer is extending to using.
Here's the shape of it: put Bitcoin (as RBTC, Bitcoin on Rootstock) into a vault, a smart-contract position only you control. Mint BPD, a dollar-pegged stablecoin, against it at 0% interest (one small fee, no annual rate). Spend the dollars. Your Bitcoin never touches a company's balance sheet, because there's no company in the middle. Repay and reclaim every coin.
What makes it radical isn't the rate. It's that the rules protecting you are code, not promises. A 110% minimum collateral ratio and a 150% recovery threshold are hard-coded, identical for everyone, and can't be quietly changed after you commit. A stability pool keeps the system solvent with no bailout. The MP token routes fees to the people keeping it healthy, not a discretionary treasury. No CEO can lend out your collateral or freeze your access, because no one holds it but you.
That's the revolution, and it's deliberately boring from the inside. It feels like paying a bill without selling, or drawing liquidity without a phone call. The drama is all in what didn't happen: no surrender, no counterparty, no permission asked.
Not risk-free: mind your collateral ratio, keep a buffer, smart-contract risk is real, and it's still early. Learn the mechanics first. But the direction only runs one way: more of ordinary financial life, minus the middleman.

Keep the keys, use the value, trust the math:
borrow against Bitcoin at 0% interest
