How to Survive a Bitcoin Crash With a Loan Still Open

Let's run the scenario nobody wants to think about until it happens.

It's a Sunday night. Bitcoin is down 18% since Friday on some headline, and you have an open loan against your stack. Your phone buzzes. What you do in the next ten minutes depends entirely on decisions you made before tonight. So let's make those decisions now, using Money Protocol — a self-custodial, 0%-interest protocol — as the worked example.

The setup that survives

Three weeks ago you deposited RBTC (Bitcoin on Rootstock) into a smart contract — your vault — and minted BPD, a dollar-pegged stablecoin, against it. You did three things right:

1. You minted at a 200% collateral ratio, not the bare-minimum 110%. Your debt is half your collateral's value.
2. You calculated your liquidation price — the BTC price at which your vault hits the 110% floor and gets closed by the protocol — and it's about 45% below where Bitcoin was on Friday.
3. You kept 20% of the borrowed BPD in reserve instead of spending all of it.

Sunday night, played out

The 18% drop is ugly, but your liquidation price is 45% down. You're not close. Your alert — which you set 25% above your liquidation price — hasn't even fired. You check the vault, confirm the ratio is still comfortably above 110%, and go to bed. That's it. That's the whole crisis, for a conservatively-opened vault.

Now rewind and imagine you'd opened at 120% to squeeze out maximum cash. That same 18% dip would have your alert screaming and your vault minutes from liquidation. You'd be racing to act at midnight. Same market, completely different night — the only variable was the ratio you chose at the start.

If you DO need to act

Say it's a deeper crash and your alert fires. You have two levers, both entirely in your hands:

• Add RBTC to the vault. More collateral, higher ratio, done — using the asset you already hold.
• Repay BPD from your reserve. Less debt, higher ratio, and your risk is permanently lower.

No phone tree. No "withdrawals temporarily paused." No support agent telling you the risk team will review your case. The protocol has no one who can freeze your assets, because liquidation is a published rule, not a human decision.

The one extra rule for true crashes

When the whole market dumps, Money Protocol can enter Recovery Mode — triggered when total system collateral falls below 150% — and in that mode, vaults under 150% can be liquidated, not just those under 110%. The practical takeaway: on the worst days, a higher buffer protects you. Borrowers sitting at 250%+ sleep through Recovery Mode entirely.

Why the responsibility is the point

A custodial lender would "handle" all of this for you — by holding your Bitcoin, earning a spread on it, and keeping the right to halt withdrawals when things get bad. Ask the Celsius and Voyager depositors how that worked out. With a self-custodial vault, the management is your job, but your coins never leave the contract and the rules can't be rewritten against you mid-crash.

Open conservatively, know your liquidation price, keep a reserve, set an alert. Do that and the scary Sunday night becomes a non-event. Full mechanics live at docs.moneyprotocol.co, and you can borrow against Bitcoin at 0% interest when you want to open a vault of your own.
