Binance and Circle deepen cooperation—what should altcoin traders pay attention to?
CoinDesk reported on September 26 that Binance invested $100 million to buy shares in Circle and signed a new five-year business agreement to promote and integrate USDC on its platform. What Binance is purchasing here is Circle equity—not something you can interpret as Binance buying an equivalent amount of altcoins.
The value of this news lies in the possibility that trading routes and liquidity structures may change. The report cited Kaiko as saying that the number of Binance USDC–denominated spot markets grew from 140 during the initial cooperation between the two in December 2024 to 329. This is the cumulative change since the cooperation began, and it cannot all be attributed to this new agreement.
【My analysis】
Stablecoin competition is not only about issuance volume—it’s also about whether users can conveniently deposit funds, exchange coins, and settle. If the trading platform expands its supported markets, it may improve the convenience of using USDC. But users’ existing USDT trading habits and liquidity won’t simply disappear overnight because of a single agreement.
For altcoin traders, the most direct question is: for the same coin, which trading pair results in lower execution cost? The additional USDC trades may come from migration of existing trading pairs, not necessarily from truly new buying power across the whole market.
Take the active trading case of $SOL as an example: as of around 13:19 Beijing time on September 27, Binance SOL/USDT spot rolling 24-hour trading volume was about $217 million in USDT. In this round, we also verified that SOL/USDC is tradeable. Here, I only use SOL as a practical example of different quote-asset pairs—it does not mean it has gained new funds solely because of this cooperation.
【My solution: look at total execution cost, not just fees】
When preparing to trade, compare the bid-ask spread between SOL/USDT and SOL/USDC based on your order amount, check order book depth, estimate slippage, and then add the USDT↔USDC exchange cost plus the actual applicable trading fees. High traded volume can be a reference, but “more activity over the past 24 hours” does not mean the order book at this moment is deep enough.
If switching doesn’t actually save you fees—because additional currency conversion and slippage end up higher—then there’s no need to switch. For small test orders, you can verify the real execution cost; for large orders, you should first evaluate price impact. Don’t treat the displayed price as fully executable for the entire intended quantity.
Going forward, monitor whether the depth of USDC trading pairs keeps improving, whether usage remains steady after any discount changes, and whether stablecoin supply and actual usage expand. If the main effect is trading migration or short-term subsidies, then you should lower your assessment of “liquidity-driven price increases from newly added liquidity.”
I care more about whether this cooperation reduces real trading friction than about using it to directly judge whether altcoins will rise or fall. The interests of Circle shareholders, USDC holders’ experience, and SOL holders’ returns are different questions.
