Braiins Invests in Bitcoin-Backed Lending Platform Firefish in a $1.8M Seed Round

Braiins–Collateralize, Never Sell

Braiins knows the importance of hodling as much bitcoin as possible. All of our revenue is in bitcoin. All of our expenses, however, are in fiat. As bitcoin maximalists, we know that we should never sell. This leaves us with one option–collateralize.

For years, we have collateralized against our stack in order to fund both current and new operations. We have used many different lenders for this, and Firefish is by far the best.

In February 2025, we collateralized with them yet again.

Firefish is tremendously easy to use. They helped us secure a $400,000 loan in just one day. There is no better partner for bitcoin-backed loans.

Firefish Marketplace Now Available in the US with USDC

Firefish offers peer-to-peer, non-custodial, bitcoin-backed loans. In other words, Firefish lets you borrow against your bitcoin without sending it to someone else–the bitcoin you get back will still be yours.

Firefish offers a solution to bitcoiners who want to avoid selling their bitcoin while still unlocking the value of it. They offer solutions for non-bitcoiners, too.

Users can also make investments on Firefish, getting secured yield on their fiat by issuing the loans to borrowers. The loans are collateralized 2-to-1, so all lenders are ensured that their money is safe.

Never sell your bitcoin–live off it. And do it on this non-custodial, peer-to-peer marketplace.

Our Investment and Plan

Because of the success of our recurring use of Firefish, we had to strengthen our partnership. So we did. We invested roughly $1,000,000 in Firefish, obtaining a 15% ownership stake in the company as part of a larger 2M USD seed round joined by a successful venture capital company, Miton C. The opportunity to unlock the value of your bitcoin–both as an individual and corporation–is life-changing.

We are thrilled to have Firefish as partners, and we are confident that their offerings will reshape bitcoin and finance as we know it.

We will integrate Firefish’s financial services into our suite of software tools to offer this value to all our clients. Our clients generate bitcoin as revenue, and so do we. Their electric bills, however, are paid in fiat–Firefish will let miners pay those electric bills without having to sell their precious bitcoin.

For now, join Firefish using code firenews to get 30% off the origination fee on your first loan.

Why Use Firefish?

Never sell your bitcoin–live off it.

Lending against your bitcoin–rather than selling it–lets you keep your bitcoin, get money for it, and avoid a taxable event. On the other hand, investing with Firefish gets you secured yield for your fiat. A ll loans carry a 50% Loan-to-Value ratio, meaning they are overcollateralized 2-to-1. A lender is always secured, as liquidation or topping-up collateral occurs in the event of bitcoin’s price dropping.

All of those metrics are easily accessible from your Firefish dashboard. You’ll receive notifications as well if bitcoin’s price approaches your liquidation price.

Bitcoiners know that bitcoin will always appreciate against fiat. Firefish lets you put your satoshis where your mouth is. Borrowing against your bitcoin is the epitome of taking a “long bitcoin, short fiat” position.
