Why a bitcoin loan you can see beats a loan nobody marks
Your bitcoin loan's LTV comes from a public price you can check any minute, so you see trouble coming. A privately marked loan can look fine until it suddenly isn't.
What mark-to-market means
Mark-to-market means the loan is revalued from a live public price, not from anyone's private opinion.
LTV (loan-to-value) is the loan divided by what the bitcoin is worth right now.
What "marking your own book" means
Marking your own book means the lender, or a model the lender chooses, sets the value of the loan. There is no public ticker for that mark.
When a loan looks shaky, the book can stay green without a default ever showing:
Extend the loan: push the due date out. The old date passes with no missed payment on the record. Pay interest in kind: skip the cash interest payment and add it to the balance instead. The borrower did not "miss" a payment. The loan just got larger.
Bankers used to joke that a rolling loan gathers no loss — keep the loan moving and you never have to write it down. That is how the structure works. It is not a claim about any named firm.
Why seeing it is better for you
A bitcoin-backed loan that marks to a public price gives you three things a private mark does not:
1. A liquidation price you can calculate yourself — the bitcoin price where the lender sells the collateral. 2. Early warning as LTV climbs, including alerts if you track the loan. 3. Time to act: add bitcoin or repay part of the loan before you hit that line.
The liquidation calculator shows that price. On the same page you can replay past bitcoin crashes against a sample loan — "Would this loan survive a real bear market?"
If you already have a loan, track this loan so the live LTV sits on a card instead of a spreadsheet.
The honest downside
Seeing the risk does not remove it. A fast crash can still liquidate you. The public price that warns you is the same price that can take the collateral. Read Bitcoin liquidation risk for how that sale works and how to leave more room.
A note on software agents
Commentators such as Anthony Pompliano and Jordi Visser talk about software that follows rules all day and night. A rule-following agent can check a public bitcoin price at 3 a.m. and act. It cannot check a private mark that never leaves the lender's book. That is a fact about the data, not a tip to put an agent in charge of a loan.
Frequently asked questions
What does mark-to-market mean on a bitcoin loan?
Mark-to-market means the loan is revalued from a live public bitcoin price, not from the lender’s opinion. Loan-to-value (LTV) is the loan divided by what the bitcoin is worth right now. When the public price moves, LTV moves with it.
What does marking your own book mean?
Marking your own book means the lender, or a model the lender chooses, sets the value of the loan. There is no public ticker for that mark. Extending the due date or adding unpaid interest to the balance can keep a default off the record. That is how the structure works, not a claim about any named firm.
Why is a public LTV easier to live with than a private mark?
A known liquidation price, early warning as LTV climbs, and time to add collateral or repay. Seeing the risk does not remove it: a fast crash can still liquidate you. BitStack is not a lender. This is not financial advice.

No. This page is education about how two loan structures work. It is not financial, tax, or legal advice, not a rate quote, and not an offer to lend.
