One of the biggest opportunities in Web3
Bitcoin was born as a digital currency in 2008, originally used for payment purposes, and over time it evolved into a value storage tool. With the rise of retail-focused Layer-1 and Ethereum Layer-2, Bitcoin's utility is facing a time of disruption. There is currently $240 billion in Bitcoin "hot money" (3.4 times the total locked volume of the entire Ethereum ecosystem) to capture and build on.
Bitcoin = individual investors
It is often believed that Bitcoin is more adopted by institutions than Ethereum. However, data shows that this is not the case. Bitcoin is mainly driven by individual investors, with 57% of the supply held by individuals and only 9.7% held by institutions (including miners). My definition of “retail investors” is non-professional investors and individuals who are more likely to be converted to Bitcoin application users due to the speculative nature of the new market.
There is currently $240 billion of “hot money” in centralized exchanges (CEX) and ETFs, which represents a huge opportunity to capture value by building a programmable layer on Bitcoin. In comparison, the total amount of Ethereum hot money on CEX is $76 billion. CEX capital is a good indicator of “hot money” because “cold money” is usually stored in cold wallets as long-term capital. ETFs can also be considered hot money because both BlackRock and VanEck have stated that more than 80% of ETF inflows come from non-professional investors using online brokerage accounts. In the hypothetical downside scenario, even if it is reduced by 50%, there is still $120 billion of Bitcoin hot money that can be deployed. Therefore, a large amount of individual investors’ capital can be deployed into Bitcoin native Dapps.
Number of Bitcoins on CEX and ETFs
Bitcoin is the most widely distributed digital asset in the world, with over 460 million unique wallets. Since the advent of Ordinals and inscriptions, the demand for Bitcoin has increased significantly. On December 19, 2022, Bitcoin's Dick Butt (pictured above) became the first inscription to be engraved on Bitcoin. Since then, Bitcoin's mempool utilization has averaged over 50% (pictured below), much higher than in the past, even reaching twice the level during the 2021 bull cycle. This shows that the demand for Bitcoin block space is very strong, but it has also caused transaction fees to rise to the point where it is difficult for ordinary users to use the chain.
Bitcoin memory pool usage
Bitcoin hot money increased by 23% between January and July 2024. During this period, the supply of Bitcoin on CEX decreased from 2.9 million to 2.7 million, while the supply of Bitcoin in ETFs increased to 890,000, resulting in a net increase of 680,000 Bitcoins. According to statistics on ETF holders and CEX hot money flows, this is mainly driven by individual investor capital.

Embracing Speculation by Individual Investors
Bitcoin may be at the beginning of a speculative cycle, which was first triggered by Ordinals, with a cumulative trading volume of $117 billion. Combined with Bitcoin-native Dapps and $240 billion in hot money, Bitcoin's speculative cycle will inevitably be longer and larger than the cycle experienced by Ethereum LRTs and Solana DeFi in early 2024. In addition, Bitcoin's individual investor adoption in terms of utility has just begun. According to research, 57% of Bitcoin is held by individuals, and only 3.4% is held by miners who usually sell mined Bitcoin for profit.

Current Scaling Solutions
Most current scaling solutions cannot effectively serve Bitcoin's large base of individual investors because they are either slow and costly or focused on institutions. For example, @Stacks, one of the earliest Bitcoin sidechains, still takes 30 minutes to complete transactions after the Nakamoto upgrade. @Lightspark is building a business-to-consumer payment solution based on the Lightning network, focusing more on merchant and institutional adoption rather than existing individual investor needs, and these solutions are still in the early stages of Bitcoin's adoption cycle. In the future, we may even see high-fidelity DeFi, such as Bitcoin open order book exchanges, perpetual protocols, and prediction markets.
A successful example of a Bitcoin hot money application is @Bounce_bit, a protocol focused on CEX hot money yields, which has reached $1 billion in Bitcoin TVL within six months of its launch. This shows that there is a strong demand among CEX users to utilize Bitcoin.
Network Effects: Rollups and Sidechains
Bitcoin is the largest and most widely distributed digital asset, and therefore has the strongest network effect in Web3. Bitcoin hot money is 3.4 times the TVL of the Ethereum ecosystem. We may be witnessing the birth of a new global Internet computer.
Since 2019, Ethereum sidechains such as Wanchain, Neo, and Ziliqa have been created as alternative solutions. At its peak, there were more than 700 PoS and EVM sidechains. However, due to technical and economic limitations, these sidechains have failed to effectively leverage Ethereum’s network effects and have been unable to successfully attract and retain developers.
In contrast, @Optimism and @Arbitrum focus on Ethereum’s network effects and work closely with Ethereum to scale its base layer. As a result, they have been more successful than EVM sidechains and have become leading scaling solutions. A similar trend is also emerging in the Bitcoin ecosystem, where multiple sidechains are being created. If history is any guide, the real winners in the Bitcoin ecosystem may be those scaling solutions that align economics, security, and incentives with Bitcoin. This means native Bitcoin gas (Bitcoin can be paid as a fee), state verification by any Bitcoin full node, and unilateral asset exits to the Bitcoin base layer.
Compared to Ethereum
Bitcoin’s hot money as a percentage of total value is similar to Ethereum’s total TVL, and this value can be unlocked by implementing programmability on Bitcoin. Ethereum L1 and L2 have a combined TVL of $71 billion, or 17% of Ethereum’s total value. Unlike Ethereum, Bitcoin’s hot money is largely underutilized, mostly stored in CEXs and ETFs. There is reason to believe that financial instruments native to Bitcoin could significantly increase its utilization.

Challenges
1. Bitcoin’s positioning as digital gold is difficult to change, resulting in low usage of scaling solutions.
Mitigation: The narrative is driven by demand, and existing data suggests that there is excess demand from individual investors for Bitcoin. Bitcoin’s positioning as digital gold may be misleading. Historically, Bitcoin's price fluctuations have not been correlated with gold prices (see figure below), but have been highly correlated with technology stocks. This suggests that the market prefers to view Bitcoin as a technological innovation rather than a store of value. Bitcoin's roots also foreshadow future programmability, as it was originally created as a utility token for payments.

2. Bitcoin will be mainly oriented to institutions, and as a decentralized payment settlement layer, Bitcoin native applications such as DeFi will find it difficult to rise.
3. Retail users are reluctant to spend Bitcoin.
Mitigation: Smart contracts through scaling solutions can unlock Bitcoin and make it a global digital currency, not just a digital asset. Before the DeFi summer of 2020, Ethereum had low utility and TVL of less than $1 billion. But with the rise of DeFi, TVL grew to $100 billion in November 2021.
Future Trends
In the next 6-12 months, the following catalysts may allow us to reproduce Ethereum’s “DeFi Summer” phenomenon on Bitcoin:
1. OP_CAT (Technical): New opcodes in the Bitcoin programming language enable verification and trustless bridging of zero-knowledge proofs, which are the missing components for creating a native scaling solution for Bitcoin. In addition, covenants and vaults will also increase the utility of Bitcoin. This upgrade only requires a soft fork because the opcodes already exist in Bitcoin’s codebase.
2. BitVM (Technical): As an alternative to OP_CAT, BitVM can perform arbitrary computations off-chain and enable the creation of trustless bridges.
3. US Monetary Policy (Monetary): Due to the US election and the policy shifts of Trump and JD Vance, it is expected that interest rates may fall by up to 50 basis points in the next 6 months, which will drive capital inflows into Bitcoin as one of the most trusted cryptocurrencies.
4. Liquidity Staking on Bitcoin: Liquidity staking driven by @babylonlabs_io can bring a new wave of liquidity to Bitcoin native applications. For reference, @Lombard_Finance was launched in September and attracted more than $260 million in Bitcoin TVL in less than a week.
