Yesterday, SOL surpassed BNB in market cap, once again becoming the fifth largest cryptocurrency by market cap. Meanwhile, Solana's early investor Multicoin Capital has released a Solana governance proposal aimed at modifying the network's current inflation model and reducing the inflation rate of its native token SOL. The proposal, numbered SIMD-0228, aims to adjust SOL's issuance rate to a dynamic and variable model to make it more market-driven.

Solana's Inflation Model Amendment Proposal, Can it Further Boost SOL Price?

The proposal sets a target staking rate of 50% to enhance the network's security and decentralization. If more than 50% of SOL is staked, the supply will decrease, thereby suppressing further staking by lowering the yield; if less than 50% of SOL is staked, the supply will increase to raise the yield and incentivize staking. The minimum inflation rate will be 0%, while the maximum inflation rate will be determined based on Solana's current issuance curve.

In Solana's mechanism, inflation refers to the issuance of SOL to the validator nodes running the Solana software and assisting in building the blockchain, with the validator nodes subsequently distributing these issuance rewards and some MEV rewards to users delegating their staked SOL.

Currently, Solana's inflation mechanism is fixed, meaning the rate at which SOL is issued as a staking reward is static and does not adjust based on market conditions. However, if this proposal is approved, the network's inflation rate will become variable and be adjusted according to market dynamics.

Reason for Proposal and Its Impact

Solana's inflation rate was initially set at 8% and planned to decrease by 15% annually until it reaches 1.5%. Data from Dune Analytics shows that the current inflation rate of SOL is around 3.7%.

Solana co-founder Anatoly Yakovenko stated on the Lightspeed podcast that the idea of a fixed inflation rate was borrowed from the design of the Cosmos blockchain, where inflation is merely a "bookkeeping mechanism." Yakovenko is not particularly concerned about inflation because the issuance of SOL does not create or destroy value but only redistributes value. Newly minted SOL is allocated to stakers, causing a relative devaluation of holdings for non-stakers.

Nevertheless, Multicoin believes that reducing SOL inflation is necessary for the following reasons:

Newly issued SOL is only allocated to stakers, which may lead to network centralization; a high inflation rate reduces the utility of SOL in DeFi and other scenarios, as the opportunity cost of non-staked SOL is too high; additionally, only 9% of staked SOL is liquid, reducing staking rewards may also reduce selling pressure in certain jurisdictions where staking rewards are considered income.

Although technically issuance does not directly cost the network as a whole, the negative perception of non-staked SOL being diluted by inflation is, in Multicoin's view, enough reason to restrict inflation.

「Given the current network activity and fees, Solana's current inflation schedule is suboptimal because it mints more SOL than necessary to secure the network,」 said proposal authors Tushar Jain and Vishal Kankani. 「This mechanism does not account for network activity and does not embed it in the inflation rate calculation.」

If the proposal is implemented and runs as expected, the authors believe that this will 「systemically reduce selling pressure while maintaining a healthy staking participation rate.」 and that 「by aligning inflation adjustments with actual deviations, the network issuance more accurately mirrors the real-time economic and security status of the network.」

This proposal also has an obvious impact — the staking yield of SOL may decrease. Currently, the SOL staking yield has historically remained above 7%; if the issuance decreases, this yield will decrease accordingly. While the growth of MEV rewards may partially offset the impact of decreased inflation, overall, the yield of staking SOL may decrease.

Community Sentiment

This proposal involves multiple stakeholders in the Solana ecosystem, and the community's views on it have inevitably varied.

Messari analyst Patryk suggested that this proposal should be adopted because Solana will evolve from 「blind issuance」 to 「smart issuance,」 which would be a positive development. He believes that the SIMD-0224 proposal is unfavorable to validators, has a neutral impact on stakers, and is favorable to SOL holders.

「Currently, the total staking reward amount of Solana far exceeds the minimum necessary amount to ensure network security. The network is mature enough and no longer requires such a high inflation rate. The SIMD-0224 proposal will change Solana's inflation rate from a fixed schedule model to a programmatic, market-driven model. This change will dynamically incentivize staking participation, similar to the model adopted by networks like @Polkadot. This will minimize inflation to the maximum extent and bring the network staking ratio closer to MNA.」

Patryk believes that this move could reduce selling pressure on SOL and decrease the current "tax burden" imposed on non-staking SOL holders.

On the other hand, Solana forum member Bji does not support this proposal. He believes that the primary purpose of inflation is to incentivize more validators to participate and maintain the network's security, and the inflation reward is meant to gradually decrease. Since Solana's plan is to gradually shift more responsibility to transaction fees to incentivize validators, the inflation reward can be reduced as a supplement.

Currently, most validators already earn significantly more from transaction fees, priority fees, and MEV than from the inflation reward. Therefore, even if the inflation reward is reduced, validators' income will not be greatly affected, but stakers' rewards may decrease.

Bji argues that if, as proposed, the inflation rate were to drop by 50%, leading to a 50% reduction in staked SOL, it is not significant because everyone would reduce their stake in the same proportion; after the proportional reduction in stake by all holders, the relative stake ratio held by validators would remain the same, so their voting power would not substantially change. Since the voting power remains unchanged, the network's security properties would also remain unchanged. Therefore, there is no reason to set a specific inflation rate target for security purposes.

Some community members also argue that yield-oriented stakers would lose motivation if the staking reward were reduced by 50%, and with a 50% decrease in total staked supply, the cost of attacking the network would also significantly decrease. "If only 20% of the total supply is staked, the distribution of stakes may remain the same, but this means that an attacker would only need to purchase and stake 10% of the total supply to halt the network."

Currently, the community is still in a wait-and-see mode regarding this proposal, with key figures in the Solana ecosystem such as Solana founder Anatoly and Helius founder Mert yet to express their views on the proposal. However, the transformation of Solana's economic mechanism is a concern for every SOL holder, with Blockworks data analyst Dan Smith stating that "Solana is officially entering an era of economic transformation."

$COIN Joins S&P 500, but Coinbase Isn't Celebrating

On May 13, S&P Dow Jones Indices announced that Coinbase would officially replace Discover Financial Services in the S&P 500 on May 19. While other companies like Block and MicroStrategy, closely tied to Bitcoin, were already part of the S&P 500, Coinbase became the first cryptocurrency exchange whose primary business is in the index. This also signifies that cryptocurrency is gradually moving from the fringes to the mainstream in the U.S.



On the day of the announcement, Coinbase's stock price surged by 23%, surpassing the $250 mark. However, just 3 days later, Coinbase was hit by two consecutive events: a hack where employees were bribed to steal customer data and a demand for a $20 million ransom, and an investigation by the U.S. Securities and Exchange Commission (SEC) into the authenticity of its claim of having over 100 million "verified users" in its securities filings and marketing materials. These two events acted as mini-bombs, and at the time of writing, Coinbase's stock had already dropped by over 7.3%.


Coincidentally, Discover Financial Services, being replaced by Coinbase, can also be considered the "Coinbase" of the previous payment era. Discover is a U.S.-based digital banking and payment services company headquartered in Illinois, founded in 1960. Its payment network, Discover Network, is the fourth largest payment network apart from Visa, Mastercard, and American Express.


In April, after the approval of the acquisition of Discover by the sixth-largest U.S. bank, Capital One, this well-established digital banking company of over 60 years smoothly handed over its S&P 500 "seat" to this emerging cryptocurrency "bank." This unexpected coincidence also portrayed the handover between the new and old eras in Coinbase's entry into the S&P 500, resembling a relay race scene. However, this relay baton also brought Coinbase's accumulated "external troubles and internal strife" to a tipping point.


Side Effects of ETFs


Over the past decade, cryptocurrency exchanges have been the most stable "profit machines." They play a role in providing liquidity to the entire industry and rely on trading fees to sustain their operations. However, with the comprehensive rollout of ETF products in the U.S. market, this profit model is facing unprecedented challenges. As the leader in the "American stack," with over 80% of its business coming from the U.S., Coinbase is most affected by this.



Starting from the approval of Bitcoin and Ethereum spot ETFs, traditional financial capital has significantly onboarded users and funds that originally belonged to exchanges in a more cost-effective, compliant, and transparent manner. The transaction fee revenue of cryptocurrency exchanges has started to decline, and this trend may further intensify in the coming months.


According to Coinbase's 2024 Q4 financial report, the platform's total trading revenue was $417 million, a 45% year-on-year decrease. The contribution of BTC and ETH's trading revenue dropped from 65% in the same period last year to less than 50%.


This decline is not a result of a decrease in market enthusiasm. In fact, since the approval of the Bitcoin ETF in January 2024, the inflow of BTC into the U.S. market has continued to reach new highs, with asset management giants like BlackRock and Fidelity rapidly expanding their management scale. Data shows that BlackRock's iShares Bitcoin ETF (IBIT) alone has surpassed $17 billion in assets under management. As of mid-May 2025, the cumulative net inflow of 11 major institutional Bitcoin spot ETFs on the market has exceeded $41.5 billion, with a total net asset value of $1214.69 billion, accounting for approximately 5.91% of the total Bitcoin market capitalization.

Institutional investors and some retail investors are shifting towards ETF products, partly due to compliance and tax considerations. On one hand, ETFs have much lower trading costs compared to cryptocurrency exchanges. While Coinbase's spot trading fee rate varies annually in a tiered manner but averages around 1.49%, for example, the management fee for IBIT ETF is only 0.25%, and the majority of ETF institution fees fluctuate around 0.15% to 0.25%.



In other words, the more rational users are, the more likely they are to move from exchanges to ETF products, especially for investors aiming for long-term holdings.


According to multiple sources, several institutions, including VanEck and Grayscale, have submitted applications to the SEC for a Solana (SOL) ETF, with some institutions also planning to submit an XRP ETF proposal. Once approved, this may trigger a new round of fund migration. According to a report submitted by Coinbase to the SEC, as of April, the platform's trading revenue from XRP and Solana accounted for 18% and 10%, nearly one-third of the platform's fee revenue.



However, the Bitcoin and Ethereum ETFs passed in 2024 also reduced the fees for these two tokens on Coinbase from 30% and 15% to 26% and 10%, respectively. If the SOL and XRP ETFs are approved, it will further undermine the core fee revenue of exchanges like Coinbase.


The expansion of ETF products is gradually weakening the financial intermediary status of cryptocurrency exchanges. From their original roles as matchmakers and clearers to now gradually becoming mere "on-ramps and off-ramps" for funds, exchanges are seeing their marginal value squeezed by ETFs.


Robinhood Takes a Stand, Traditional Brokerages Join the Fray


On May 12, 2025, SEC Chairman Paul S. Atkins gave a keynote speech at the Tokenization and Cryptocurrency Working Group roundtable. The theme of his speech revolved around "It is a new day at the SEC," where he indicated that the SEC would not approach enforcement and regulation the same way as before but would instead pave the way for cryptocurrency assets in the U.S. market.



With signs of cryptocurrency compliance such as the SEC's "NEW DAY" declaration, an increasing number of traditional brokerages are attempting to enter the cryptocurrency industry. One of the most representative cases is the well-known U.S. brokerage Robinhood, which began expanding its crypto business in 2018. By the time of its IPO in 2021, Robinhood's crypto business revenue accounted for over 50% of the company, with a significant boost from the Dogecoin "moonshot" promoted by Musk.


In Q1 2025 earnings report, Robinhood showcased strong growth, especially in revenue from cryptocurrency and options trading. Fueled by Trump's Memecoin, cryptocurrency-related revenue reached $250 million, nearly doubling year-over-year. Consequently, Robinhood Gold subscription users reached 3.5 million, a 90% increase from the previous year, with the rapid growth of Robinhood Gold providing the company with a stable source of income.



Meanwhile, RobinHood is actively pursuing acquisitions in the cryptocurrency space. In 2024, it announced a $2 billion acquisition of the long-standing European cryptocurrency exchange Bitstamp. Additionally, Canada's largest cryptocurrency CEX, WonderFi, which recently went public on the Toronto Stock Exchange, also announced its integration with RobinHood Crypto. After obtaining virtual asset licenses in the UK, Canada, Singapore, and other markets, RobinHood has taken a proactive approach in the compliant cryptocurrency trading market.



Furthermore, an increasing number of brokerage firms are exploring the same path. Futu Securities, Tiger Brokers, and others are also dipping their toes into cryptocurrency trading, with some having applied for or obtained the VA license from the Hong Kong SFC. Although their user bases are currently small, traditional brokerages have a natural advantage in user trust, regulatory licenses, and low fee structures. This could pose a threat to native cryptocurrency platforms in the future.



User Data Breach: Is Coinbase Still Secure?


In April 2025, security researchers discovered that some Coinbase user data was leaked on the dark web. While the platform initially responded by attributing it to a "technical misinformation," it still raised concerns among users regarding its security and privacy protection. Just two days before Dow Jones Indexes announced Coinbase's addition to the S&P 500 Index, on May 11, 2025, Coinbase received an email from an unknown threat actor claiming to have obtained customer account information and internal documents, demanding a $20 million ransom to keep the data private. Subsequent investigations confirmed the data breach.


Cybercriminals obtained the data by bribing overseas customer service agents and support staff, mainly in "non-U.S. regions such as India." These agents abused their access to Coinbase's internal customer support system and stole customer data. As early as February this year, blockchain detective ZachXBT revealed on X platform that between December 2024 and January 2025, Coinbase users lost over $65 million to social engineering scams, with the actual amount potentially higher.


Among the victims was a well-known figure, 67-year-old Ed Suman, an established artist in the art world for nearly two decades, having been involved in the creation of artworks such as Jeff Koons' "Balloon Dog" sculpture. Earlier this year, he fell victim to an impersonation scam involving fake Coinbase customer support, resulting in a loss of over $2 million in cryptocurrency. ZachXBT critiqued Coinbase for its inadequate handling of such scams, noting that other major exchanges have not faced similar issues and recommending Coinbase to enhance its security measures.


Amidst a series of ongoing social engineering incidents, although there has not been any impact on user assets at the technical level so far, it has raised concerns among many retail and institutional investors. Especially institutions holding massive assets on Coinbase. Just considering the U.S. BTC ETF institutions, as of mid-May 2025, they collectively hold nearly 840,000 BTC, and 75% of these are custodied by Coinbase. If we price BTC at $100,000, this amount reaches a staggering $63 billion, which is equivalent to the nominal GDP of two Iceland in the year 2024.

In addition, Coinbase Custody also serves over 300 institutional clients, including hedge funds, family offices, pension funds, and endowments. As of the Q1 2025 financial report, Coinbase's total assets under management (including institutional and retail clients) reached $404 billion. The specific amount of institutional custodied assets was not explicitly disclosed in the latest report, but it should still be over 50% based on the Q4 2024 report.

Once this security barrier is breached, not only could the rate of user attrition far exceed expectations, but more importantly, institutional trust in it would undermine the foundation of its business. Therefore, after a hacking event, Coinbase's stock price plummeted significantly.


CEXs are All in Self-Rescue Mode


Facing a decline in spot trading fee revenue, Coinbase is also accelerating its transformation, attempting to find growth opportunities in derivatives and emerging assets. Coinbase acquired a stake in the options platform Deribit at the end of 2024 and announced the official launch of perpetual contract products in 2025. This acquisition fills in Coinbase's gap in options trading and its relatively small global market share.



Deribit has a strong presence in non-U.S. markets, especially in Asia and Europe. The acquisition has enabled Coinbase to gain a dominant position in bitcoin and ethereum options trading on Deribit, accounting for approximately 80% of the global options trading volume, with daily trading volume remaining above $2 billion.


Meanwhile, 80-90% of Deribit's customer base consists of institutional investors, with their professionalism and liquidity in the Bitcoin and Ethereum options market highly favored by institutions. Coinbase's compliance advantage, coupled with its already robust institutional ecosystem, makes it even more suitable. By using institutions as an entry point, it can face the squeeze from giants like Binance and OKX in the derivatives market.



Facing a similar dilemma is Kraken, which is attempting to replicate Binance Futures' model in non-U.S. markets. Since the derivatives market relies more on professional users, fee rates are relatively higher and stickiness is stronger, making it a significant source of revenue for exchanges. In the first half of 2025, Kraken completed the acquisition of TradeStation Crypto and a futures exchange, aiming to build a complete derivatives trading ecosystem to hedge the risk of declining spot transaction fee income.


With the surge of Memecoin in 2024, Binance, OKX, and various CEX platforms began massively listing small-market-cap, highly volatile tokens to activate active trading users. Due to the wealth effect and trading activity of Memecoins, Coinbase was also forced to join the battle, successively listing popular tokens from the Solana ecosystem such as BOOK OF MEME and Dogwifhat. Although these coins are controversial, they are frequently traded, with fee rates several times higher than mainstream coins, serving as a "blood-boosting" method for spot trading.


However, due to its status as a publicly traded company, this practice is a riskier endeavor for Coinbase. Even in the current crypto-friendly environment, the SEC is still investigating whether tokens like SOL, ADA, and SAND constitute securities.


In addition to the forced transformation strategies carried out by the aforementioned CEXs, they are also starting to lay out RWAs and the most talked-about stablecoin payment fields, such as the PYUSD launched through a collaboration between Coinbase and Paypal, Coinbase's support for the Euro stablecoin EURC by Circle that complies with EU MiCA regulatory requirements, or the USD1 launched through a collaboration between Binance and WIFL. In the increasingly crowded trading field, many CEXs have shifted their focus from just the trading market to the application field.


The golden age of transaction fees has quietly ended, and the second half of the crypto exchange platform game has silently begun.
