Martin Connor’s book linking Bitcoin, lending and collateral, with a strong focus on Firefish. Alongside its case for this model, we specify which passages we read and their limitations.
Martin Connor is the main author of the book published by Braiins in 2024. The publisher lists 111 pages; the public English PDF also has 111 pages. We checked its publication details directly. [1] [2]
The book explores using bitcoin as collateral to obtain a loan without initially selling the coins held. The word “ultimate” expresses its thesis, not an independent ranking of all financing options. [1]
Firefish distinguishes the borrower who pledges bitcoin from the investor who lends funds for interest. Drawing a loan therefore creates a repayment obligation; it is not a return from merely holding bitcoin. [4]
The passage on pages 49–51 describes liquidation following nonpayment or a decline in collateral value. It presents collateral top-ups and early repayment as possible responses. It does not guarantee that borrowers can fund them. [2]
The book gives specific loan parameters. The current FAQ considers the amount due including interest and fees. We therefore do not transfer the book’s figures to today’s offer or treat them as contractual terms. [2] [4]
The publisher acknowledges that Braiins uses Firefish. We therefore also read the examples and advocacy for collateral in the context of the participating companies’ business experience, rather than as an independent provider audit. [3]
Keeping coins when drawing a loan does not mean retaining them in every circumstance. The book itself and the service documentation allow for liquidation. We read the opening slogan together with this condition. [1] [2] [4]
We checked title and publication details, the contents, pages 26–29 and 48–51 of the English PDF, the publisher’s description and the service FAQ. We did not review the whole book or test a loan or its technical security. [1] [2] [3] [4]
For the clearest picture, read this entry together with Bitcoin, Fiat money, Multisig, Braiins. The reverse links also lead from The Bitcoinization of Finance.
01Does the title mean that borrowing is risk-free?+
No. The title states the author’s thesis. The passage read explicitly describes liquidation after nonpayment or a fall in collateral value.
02Can the book establish today’s borrowing cost?+
Not reliably. Interest, fees, maturity and collateral rules must be read in the current offer and contract; the book describes conditions at the time.
