Frequently asked questions

Can I use Bitcoin for a down payment without selling?

Yes, in this model you pledge Savings-bucket Bitcoin instead of selling it. The published example posts $250,000 of BTC to receive $100,000 (250% collateral / 40% credit). Selling the same $100,000 down payment removes the coins. BitStack is not a lender and this page is not a loan offer.

Which of four buckets (Savings / Investments / Income / Other) can fund a down payment?

Only Savings — self-custodied BTC — inside four buckets (Savings / Investments / Income / Other). Investments (MSTR, miners), Income (yield without selling BTC), and Other (legacy assets not yet converted) are not pledgeable collateral in the BitStack calculators. The buckets explain why you own each asset. They are not a recommended mix and not a loan product.

What does the 250% pledge rule mean?

250% collateralization means you post two and a half times the credit in Bitcoin. At 40% credit, pledging $250,000 of BTC corresponds to $100,000. The published example does not liquidate when the Bitcoin price drops. It is an education example, not an application.

How is a cash-out Bitcoin loan different from pledging?

A cash-out loan is sized by loan-to-value: dollars borrowed divided by Bitcoin value. In the down-payment calculator, 50% origination can liquidate after a 50% dump scenario, 35% can margin-call, and 30% origination stays healthy. The pledge example does not liquidate on a dump. BitStack models both. It does not lend.

What LTV stays healthy after a 50% BTC dump?

30% origination stays healthy in the published calculator scenario (not a forecast). Originate at 30% LTV — the 30% rule in this model. After a 50% dump, cash-out math (65% margin call, 80% liquidation) takes 30% origination to 60% LTV (healthy), 35% origination to 70% (margin call), and 50% origination to 100% LTV (liquidated). The 50% dump is a scenario toggle, not a forecast. Calculator: https://trybitstack.com/tools/down-payment-calculator. Learn: https://trybitstack.com/learn/down-payment-without-selling.

How much BTC do I pledge per $1 of down payment?

~$2.50 of Savings-bucket BTC per $1 credit (250% collateral / 40% credit). The published example posts $250,000 of Savings-bucket BTC to receive $100,000. Only Savings-bucket BTC is pledgeable. Education only. BitStack is not a lender.

What is bitcoin-backed borrowing / LTV in 2026?

Bitcoin-backed borrowing means posting Bitcoin as collateral to receive dollars or stablecoins without selling the coins. Loan-to-value (LTV) is the loan divided by Bitcoin collateral, as a percent. Ranges already described on BitStack pages are usually 25% to 50% loan-to-value at origination. BitStack tracks loans you already have; not a lender. Formula: LTV = (Loan Amount ÷ Collateral Value) × 100% in https://trybitstack.com/llms-full.txt.

Sell vs pledge vs cash-out refinance for BTC holders

Sell: a $100,000 down payment means selling about $100,000 of Bitcoin at spot. The stack is gone. Pledge: post $250,000 of Savings-bucket BTC to receive $100,000 (250% collateral / 40% credit). A price dump does not liquidate that published example. Cash-out refinance in this model is the cash-out Bitcoin loan — dollars borrowed divided by BTC value. A 50% dump scenario takes 50% origination to liquidation, 35% origination to a margin call, and 30% origination stays healthy. The 50% dump is a scenario, not a forecast. Education only. BitStack is not a lender.
