Introduction

For most of its existence, Bitcoin has established itself as a store of value. This view, however, is no longer the case in 2025. 

Bitcoin Finance (BTCfi) has brought Bitcoin into a new position. Now, it exists as a means to generate yield, secure networks, and support decentralized finance.

BTCfi protocols allow Bitcoin and Bitcoin-backed assets to be part of the DeFi ecosystem without jeopardizing the founding principles of Bitcoin. 

Use cases like restaking, yield tokenizing, and cross-chain liquidity have seen widespread adoption, making retail and institutional clients interested.

As BTCfi grows in maturity, specific protocols stand out as overall market leaders and are worth focusing on as up-and-coming coins in the BTCfi market. 

This CoinEx article will give you a list of the top five BTCfi protocol coins to pay attention to in December 2025.

What is BTCfi?

Understanding Bitcoin Finance (BTCfi)

BTCfi represents the DeFi protocols that maximize the utilization of Bitcoin beyond merely holding or trading. Such DeFi protocols make it possible to use BTC or assets linked to BTC productively across DeFi ecosystems.

Typical use cases for BTCfi include:

• Bitcoin restaking and shared security
• Yield generation through structured products
• Cross-chain Bitcoin liquidity
• BTC-backed derivatives and synthetic assets

BTCfi is not like the Ethereum-centric DeFi solutions that have emerged so far. Its job is to efficiently make Bitcoin a part of the decentralized financial infrastructure.

Why BTCfi Matters

BTCfi enhances the use of Bitcoin in the crypto economy. It gives Bitcoin holders the chance to earn yield, support network security, and participate in DeFi while maintaining Bitcoin exposure. 

This process makes BTCfi an essential link between Bitcoin and DeFi.

• Market capitalization and liquidity
