Bitcoin & Credit

Instead of selling your bitcoin, you can pledge it as collateral for a loan. Providers differ a lot in whether they custody your bitcoin themselves or secure it via on-chain multisig escrow, and in how they are regulated.

Our pick

Firefish

Headquarters
Prague, Czechia
Founded
Founded in 2022 by Martin Matejka and Igor Neumann
Regulation
Firefish Europe s.r.o. is authorized as a crypto-asset service provider (CASP) under the EU's MiCA regulation

Founders
Martin Matejka and Igor Neumann
Current leadership
Founding team still leading operations
Investors

Strengths
  • Non-custodial: bitcoin sits in a multisig escrow on the Bitcoin blockchain, not with Firefish itself
  • MiCA-licensed via Firefish Europe s.r.o.
  • Rates from 5% p.a., no monthly instalments, repayment at the end of the term
  • No credit check needed, owning bitcoin is enough
Weaknesses
  • Young company (since 2022), shorter track record than established banks
  • Marketplace model: terms also depend on available lenders
  • Escrowed bitcoin gets liquidated if the loan isn't repaid
Best for: Bitcoin holders who value non-custodial storage via multisig escrow and want a loan against their bitcoin without a credit check.
