Bitcoin (BTC) has always been the face of crypto, the first thing that comes to mind when you think of this market. But for years, its role has been largely static—held as a store of value, yet rarely used for anything else. Then BTCFi entered the scene: unlike traditional DeFi, which has been dominated by Ethereum (ETH) and other smart contract platforms, BTCFi is built around Bitcoin as the core asset.

In the last quarter of 2024, BTCFi’s total value saw a massive surge—from $800 million all the way to $6.5 billion. The momentum is impressive, to say the least. More institutional players are taking notice, and analysts predict that by 2030, roughly 2.3% of Bitcoin’s circulating supply (about $47 billion) could be actively used in decentralized finance. 

So clearly, BTCFi is not just a passing trend. But why is it gaining so much traction? Can it really be called the future of Bitcoin’s utility as a financial asset?

Let’s try to figure it out.

What is BTCFi, and why is it growing now?

BTCFi represents the intersection of Bitcoin and decentralized finance, with the first crypto playing the role of the core asset in this case. Typically, DeFi platforms have been built on blockchains like Ethereum, while Bitcoin holders had to wrap their BTC into ERC-20 tokens (like wBTC) to participate in this field.

This kind of tokenization started picking up the pace around 2020, allowing BTC holders to access DeFi services that are typically not available on the Bitcoin blockchain. These “wrapped” tokens are built in a way that makes them compatible with other blockchain networks. And so, they effectively extended Bitcoin’s functionality.

However, advancements in Bitcoin L2 solutions and LRTs, or layered rollup technologies, are now changing the rules. It is becoming unnecessary for Bitcoin to use “second class citizen” ERC-20 tokens anymore.

BTC LRTs, for example, operate on Ethereum and other chains as well, but use Bitcoin as the primary collateral in transactions. This means unlocking the use of Bitcoin as a yield-generating asset in other networks beyond its native chain.

The emerging Bitcoin L2s, meanwhile, are tackling this blockchain’s long-standing scalability issues, allowing for faster and more cost-efficient transactions. These innovations are going to fundamentally redefine Bitcoin, turning it from a passive store of value to an actively utilized financial asset.

Why is BTCFi the gateway for Bitcoin whales in 2025?

Large Bitcoin holders—miners, in particular—have often used CeFi loans backed by their BTCs to fund their operations since they didn’t want to outright sell those assets. This practice is still going on today, but BTCFi promises to make some changes. And that’s where everything will start from, really: by BTCFi enabling new opportunities for Bitcoin holders to put their assets to work.

Soon enough, Bitcoin whales will start looking at BTCFi as a powerful gateway that can be used to enter the DeFi space. And the way I see it, there are two key factors in 2025 that will influence that perception.

The first is the rise of Bitcoin ETFs. BTC ETFs currently account for almost 6% of all Bitcoin supply, having crossed $100 billion in holdings at the beginning of 2025. With them gaining mainstream traction, Bitcoin is increasingly perceived as the safest and most stable cryptocurrency asset.

This makes it a prime choice for DeFi, attracting large-scale holders who want to use their BTC without selling. Earlier in February this year, Goldman Sachs announced that it had invested $1.63 billion in Bitcoin ETFs. That’s easy proof right there.

The second major factor is the appearance of BTC L2 technologies, which we’ve already covered earlier. Until recently, the lack of scalability and transaction efficiency held Bitcoin back from DeFi adoption. Now, we are going to see a surge of L2 solutions that will enhance the network’s performance. And here’s the important part: they will do so while preserving Bitcoin’s core principles of decentralization and simplicity (and, hence, its robustness).

What DeFi platforms need to do for proper BTCFi integration

There are several challenges that will need to be overcome before BTCFi can achieve truly seamless integration. The biggest technical issue will be ensuring that Bitcoin-based L2 solutions become genuinely trustless. At the present time, they are not quite there, often relying on intermediaries and centralized elements, which goes against Bitcoin’s core philosophy.

The good news is that there’s a lot of R&D going on to make it happen. If successful, it could make the vast amounts of BTCs that are currently just lying there “collecting dust” be useful in DeFi.

Another big challenge is going to stem from people’s trust. Among Bitcoin holders, there are many who do not quite trust Ethereum and the existing Bitcoin tokenization methods. The key to winning them over will lie in creating robust and cost-effective solutions on the native Bitcoin network. Having a fully trustless and inexpensive execution layer on the BTC blockchain could really become the dealbreaker for these people.

The future of Bitcoin: More than just ‘digital gold’

For years, Bitcoin has been carrying the moniker of “digital gold”—a safe-haven asset meant for holding rather than using. These days, this is becoming increasingly untrue. As more institutional players enter the crypto space, the potential for BTCFi to become Bitcoin’s next-level evolution is very real.

The demand is on the rise, and the infrastructure is already being built. For Bitcoin whales looking to maximize their assets without selling, BTCFi could become the perfect answer.

He is a founder of Curve Finance, a decentralized exchange designed for efficient and low-slippage trading of stablecoins. Since the inception of Curve Finance in 2020, Michael has developed all his solutions and products independently. His extensive scientific experience in physics, software engineering, and cryptography aids him in product creation. Today, Curve Finance is one of the top three DeFi exchanges regarding the total volume of funds locked in smart contracts.

Law enforcement in India has arrested five suspects who allegedly duped a businessman out of roughly $700,000 via a fake cryptocurrency trading platform.

According to local media, the five suspects, including one woman, were taken into custody following an investigation by the cybercrime wing of Odisha’s Crime Branch. 

The accused reportedly ran a scam using a bogus trading app called ZAIF, where they promised massive returns of up to 200% on digital currency investments. The trading platform was promoted as being based in Japan.

It’s worth noting that ZAIF is the name of a legitimate Japanese cryptocurrency exchange, which suffered a $60 million hack in 2022. However, the platform used in this scam is likely unaffiliated and merely borrowed the name to appear credible.

The fraud kicked off when the victim, an Indian businessman, was contacted on Facebook by a woman claiming to be a Hong Kong-based IBM software developer. 

She gained his trust and convinced him to invest in crypto via ZAIF. Over a month, he transferred more than INR 6 crore (approximately $$699,352) across various accounts controlled by the scammers.

As is common in such crypto trading scams, the victim was initially shown fake profits on the platform to build trust. However, when the victim attempted to withdraw gains, the platform demanded an additional INR 89 lakh to unlock the funds — a tactic commonly referred to as an advance fee fraud.

Once the victim refused, the scammers vanished, cutting off contact.

Police tracked down the suspects through digital trails and banking records. Authorities seized phones, SIM cards, ID documents, and other incriminating materials during a raid.

With cryptocurrencies still operating in a grey area, India remains a hotspot for scams and fraud targeting unsuspecting users. Earlier this month, police cracked down on a similar scam that promoted a fake token called RSN and promised 2% daily returns. Losses were estimated to be between $1.14 and $2.29 million.

Crypto observers were speculating on Monday that World Liberty Financial (WLFI), the decentralized finance (DeFi) platform backed by U.S. President Donald Trump and his family, might be testing its long-awaited dollar stablecoin before rolling out for the broader public.

Blockchain sleuths earlier today noted a flurry of activity with a token labeled as World Liberty Financial USD (USD1) on blockchain monitoring websites Etherscan and BscScan. Blockchain data shows that USD1 was deployed earlier this month on the Ethereum and BNB Chain networks and series of transactions with the token occurring over the past couple weeks.

Some transfers included addresses linked to Wintermute, a large digital asset trading firm and market maker, and crypto custodian BitGo, according to Arkham Intelligence data. The token’s supply currently stood at around 3.5 million-3.5 million on Ethereum and BNB Chain, per Etherscan and BscScan.

Changpeng CZ Zhao, founder of crypto exchange giant Binance, brought widespread attention to the token by “welcoming” the project on BNB Chain in a post with a screenshot of the USD1 BscScan profile shared with his 10 million followers. The post, he later said, triggered a wave of copy-cats aiming to capitalize on the new-found attention.

WLFI, reacting in a X post, said USD1 is not currently available for trading and crypto users should beware of scams.

Stablecoin buzz

WLFI, a project spearheaded by Zachary Folkman and Chase Herro, made a splash last year as one of the first crypto projects enjoying the backing of Trump. The protocol aims to provide a blockchain-based marketplace where users can borrow and lend cryptocurrencies, create liquidity pools and transact with stablecoins.

It’s been widely known that the project is working on crafting its own stablecoin, but there hasn’t been any official communication about exact plans and timing of launching the token publicly. CoinDesk has reached out to the team, but hasn’t received any replies.

Stablecoins are one of the fastest-growing corners of the crypto industry and widely regarded as the killer use case for blockchains. With their prices pegged to an external asset, predominantly to the U.S. dollar, they are widely used as a crypto trading pair and transactions on blockchain rails. They are also increasingly used for everyday payments, remittances and savings, attracting the attention of many venture capital investors.

Buzz around the asset class rejuvenated over the past months as the Trump administration elevated stablecoin regulation to the top of its crypto agenda. Treasury Secretary Scott Bessent said that stablecoins have a key role in preserving the U.S. dollar’s global role as a reserve currency.
