Company details
Written by the company
Firefish is a global, non-custodial platform that enables users to access cash or stablecoins by using Bitcoin as collateral—without ever needing to sell it. Whether you're looking to borrow or earn, Firefish connects people directly in a secure, peer-to-peer marketplace. Security and transparency are at the core of everything we do. Bitcoin collateral is stored in a multi-signature escrow, where no single party—including Firefish—can access your funds unilaterally. This decentralized model removes the risks common with centralized lending platforms. Borrowers receive loans in traditional currencies or stablecoins, while retaining their Bitcoin exposure. Investors earn interest by funding loans backed by overcollateralized Bitcoin, all without needing to handle crypto directly. Available to users in supported countries around the world, Firefish makes lending and borrowing simple, transparent, and secure. Our platform is built on open, auditable technology and supports multiple languages, making it accessible and user-friendly for everyone. Firefish: Keep your Bitcoin. Unlock its value.

Firefish is truly a game changer. Amazing work.
I've had the opportunity to work with Firefish, and I'm genuinely impressed. This is a trusted platform that represents a real breakthrough.
Simply amazing. Highly recommended.
167 loans in -- service is great
I draw over 160 loans already and everythings works just fine. Thank you Firefish, great service.
Absolutely trustworthy!
The platform is entirely transparent and absolutely trustworthy!
The services are customer friendly and the support responds quickly if needed.
There is no better provider for BTC backed lending than Firefish!
Easy to use
Everything is easy to use and intuitive. Great service for someone who needs money and doesn´t want to sell BTC. Also great service for someone who doesn´t want to touch BTC but wants to earn some interest. Highly recomended.
Best lending-and borrowing-Platform in BTC/Crypto in Europe so far
On the Firefish-platform you can borrow money in Euro or USDC against your BTC -- similar how to borrow money against your real estate in tradFi (If you own the real estate).
You don't sell your BTC, you deposit it via a smart contract and when you pay back your loan, you get your Btc-collateral back to your Wallet.
It's much easier to borrow Cash against your BTC on Firefish than borrow Cash in a traditionell bank: you only have to own BTC.
You also can lend cash for round 10% interest (per year): These are new financial opportunities in the btc- and cryptoSpace for retail that tradfi doesn't offer.
Firefish is easy to use: download the FireFish-App, make KYC and you can start.
An example: If you want borrow 10.000€, you have to send BTC as a collateral in double value. If the current price of BTC is (for example) 100.000€, you have to send 0.2 BTC as a collateral (Double value of your borrowed 10.000€). You can choice to pay the loan back in 3 -24 month. You have to do it in time otherwise you get liquidated. But the Firefish-Team send you sevaral messages to remind you.
The Firefish-Team has a great support: they react fast and they are very competent. If you have any question or problem they help you 24/7 - even on a sunday.
Firefish has a good reputation in cryptoSpace and CryptoAnalysts like "Blocktrainer" recommends it.
Very positive experience on my side
Very positive experience on my side. Everything was working correctly and I was able to go though the whole loan process like a charm. Also I need to appreciate fast and communicative support
Fast, Easy, and You Keep Your Bitcoin!
I am super satisfied with Firefish! The entire process went off incredibly smooth, and the platform is intuitive and easy to use. I got my loan deal matched in a matter of hours. It puts you in control, which is way better than dealing with traditional banks. On of the biggest benefit is the ability to leverage my assets without ever having to sell my Bitcoin!

You don't sell your Bitcoin, you pawn it.
You don't sell your Bitcoin, you pawn it.
So far, I've only had positive experiences as both a borrower and a lender. And by the way, regardless of the respective "orders," I've also had good contact with support; the Telegram group is primarily used to clarify questions. The community is also on board. I'm now eagerly awaiting the Bitcoin-backed credit card that's supposed to arrive and the rollover loan feature.
So far, as of June 17, 2025, I've had only positive experiences.
And the interest rates are, of course, always too high or too low, depending on the lender or lending position. Just kidding, it's okay. :-)
The only criticism: contract documents are in English. At least so far, they weren't available in the local language. When it comes to financial matters, I expect something different in terms of quality for the customer. And not just a quick AI translator. This has to be formulated in a legally secure/binding manner in all languages where users are addressed.

Got the loan pretty fast (2 days)
Got the loan pretty fast (2 days), no documentations, complications, just bitcoin transaction and money was on my bank acc.
I'm happy with the seamless workflow, I felt always in control and got the amount and the fee I was looking for. All good for now.
As a selfemployed person your credit…
As a selfemployed person your credit score can drop due to many reasons very easy. I had no chance to get a loan from any old school bank. Firefish helped me to get out of that struggle. 4 loans all approved within a few days. 3 of them already paid back and got my bitcoin back immediately. Everything worked just as described. And the support answered within a few hours. Bitcoin and Firefish is the combination I needed in my situation! 100% recommendation.
Legit business, simple and powerful tool.
Legit business, totally transparent and well thought out, saves tons of headache for both lender and borrower. I got my money back on time - and if I did not, very sure Firefish would have paid me out from the collateral. These folks are real and you can meet them in person and discuss the platform on various public events.
