<p>Crypto exchange acquisitions have come under the spotlight after Binance founder <a href="https://x.com/cz_binance/status/2081319002589302993" rel="noopener noreferrer nofollow">Changpeng Zhao warned</a> that buying smaller trading platforms could expose buyers to hidden security risks.</p>
<p>His comments followed separate decisions by BitMart and BitMEX to wind down their exchange operations. Zhao said an acquisition does not only transfer customers and trading activity, it can also pass along legacy vulnerabilities, outdated infrastructure, and security weaknesses that remain undiscovered until after a deal closes.</p>
<h2 id="h-crypto-exchange-acquisitions-raise-security-questions" class="wp-block-heading"><strong>Crypto Exchange Acquisitions Raise Security Questions</strong></h2>
<p>Zhao <a href="https://x.com/WuBlockchain/status/2081371865591820417?s=20" rel="noopener noreferrer nofollow">said</a> purchasing a smaller centralized exchange differs from acquiring many other businesses because security risks may remain hidden for years. According to him, an exchange buyer could inherit legacy backdoors or software weaknesses created by previous teams.</p>

<p>Those issues may only become visible after ownership changes, increasing the risk of a future security breach.</p>
<p>He added that <a href="https://www.thecoinrepublic.com/2026/01/31/u-s-treasury-sanctions-uk-crypto-exchanges-over-iran-sanctions-evasion/" rel="noopener noreferrer nofollow">crypto exchange</a> acquisitions remain possible but require greater caution because technical risks extend beyond financial considerations. Zhao had shared a similar view in February 2020 via a <a href="https://www.binance.com/en/blog/from-our-ceo/421499824684900429" rel="noopener noreferrer nofollow">Binance blog</a>. In that blog, he stated that smaller exchanges faced greater exposure to hackers because they generally operated with weaker security protections than larger platforms.</p>
<p>His latest comments also focused on infrastructure rather than business metrics. Zhao noted that security decisions begin with system architecture, database design, credential storage, and key management.</p>
<p>Those foundations cannot be replaced quickly after an acquisition. He suggested fixing deeply embedded weaknesses could cost more than building new systems.</p>
<p>The warning followed reports that BitMart joined BitMEX in announcing plans to exit the exchange business.</p>
<h2 id="h-bitmart-wind-down-sets-timeline-for-customers" class="wp-block-heading"><strong>BitMart Wind-Down Sets Timeline for Customers</strong></h2>
<p><a href="https://www.bitmart.com/en-US/support/articles/7922665245339/39162120325403/53544595916059" rel="noopener noreferrer nofollow">BitMart stated</a> that it reviewed its operating conditions, market environment, and strategic direction before deciding to close its trading platform. The company did not identify a single reason behind the decision.</p>
<p>The exchange immediately suspended new registrations, deposits, and new trading orders after publishing its notice. Futures accounts entered reduce-only mode, while existing spot users could no longer place fresh orders. BitMart also confirmed that copy trading, staking, lending, Launchpad, and grid trading products would close under separate schedules.</p>
<p>All trading services will stop on Aug. 26 at 01:00 UTC. In addition, the platform operations will officially end on Jan. 31, 2027, at 15:59 UTC. Customers can continue withdrawing assets during the wind-down period. However, BitMart said withdrawal requests may still require identity verification, address screening, source-of-funds checks, and sanctions reviews.</p>
<p>The company also warned that processing times could increase if many users request withdrawals near the final deadline.</p>
<p>In addition, BitMEX also <a href="https://www.thecoinrepublic.com/2026/07/26/bitmart-shuts-crypto-exchange-as-bmx-token-crashes-nearly-63/" rel="noopener noreferrer nofollow">confirmed</a> it will close on Sept. 23 after operating for 11 years. The exchange became widely known for introducing perpetual swap contracts. Separately, EXMO began winding down operations after Britain placed the platform on a Russia-related sanctions list.</p>
<h2 id="h-crypto-exchange-closures-extend-beyond-bitmart-token" class="wp-block-heading"><strong>Crypto Exchange Closures Extend Beyond BitMart Token</strong></h2>
<p>Market activity changed following the announcement. <a href="https://coinmarketcap.com/currencies/bitmart-token/" rel="noopener noreferrer nofollow">CoinMarketCap data</a> showed the BMX price dropped to about $0.08, representing a 58% decline over 24 hours. The token’s market capitalization fell to roughly $27 million. Its price also remained nearly 70% below levels recorded during the past year.</p>
<p>BitMart recorded about $1.6 billion in daily trading volume, a 51% increase from the previous period. Bitcoin accounted for almost half of that activity.</p>
