I went straight to BitMart’s official shutdown notice on this one, because secondhand summaries never tell you as much as the announcement itself.
The exchange’s own support page says the decision came after “careful evaluation of the Company’s operating conditions, market environment, and future strategic direction,” and that BitMart would commence an orderly wind-down of its trading platform operations
Reading that line a few times, I keep landing on the same thought: it’s the kind of sentence you write when you don’t want to name the actual reason. The mechanics underneath it are far more concrete, though, new registrations and all deposit services began being gradually suspended from July 26, 2026, at 01:30 UTC.
What struck me most was the fraud warning tacked onto the end of the notice, where BitMart felt it necessary to remind its own users that it would never ask for an “expedited processing fee” or “account unfreezing fee.” That’s not a line you include unless you’re bracing for scammers to swarm the wreckage.
Where BitMart Stood on Volume and Price
I pulled the numbers myself rather than trust anyone’s paraphrase of them. CoinMarketCap’s live rankings put Binance, Coinbase Exchange, Upbit, OKX, and Bybit at the top of the spot volume table, and the platform notes it tracks 243 spot exchanges with a total 24-hour volume of $812.92 billion. BitMart isn’t anywhere near that visible top tier, and honestly, it hadn’t been for a while, this wasn’t a sudden fall from grace so much as a slow slide nobody wanted to talk about out loud.
The token tells the same story faster. CoinMarketCap’s BMX page shows it ranked around #719 by market cap, sitting near $19 million, and the page itself is now headlined with “BitMart To Shut Down After 9 Years, BMX Token Drops 58%.” There’s something almost brutal about watching a market data page turn into an obituary in real time.
The 2021 Hack, In the Company’s and Security Firm’s Own Words
This is the part of the story I think gets glossed over too easily, so I went back to the original statements instead of anyone’s recap of them. BitMart’s own CEO, Sheldon Xia, posted directly on his X account at the time: “We have identified a large-scale security breach related to one of our ETH hot wallets and one of our BSC hot wallets… The hackers were able to withdraw assets of the value of approximately USD 150 million,” and confirmed BitMart was temporarily suspending withdrawals until further notice. Reading that now, five years later, with the shutdown notice sitting right next to it, it reads less like an isolated incident and more like the opening chapter of a story that never really got resolved.
The security firm that actually caught the breach put a number on it before BitMart did. PeckShield’s own post at the time read simply: “Total estimated loss: ~200M (~100M on Ethereum and ~96M on Binance Chain).” No spin, no corporate softening, just the number.
The Reserve Promise BitMart Never Actually Kept
This is the part I want to be precise about, because it’s easy to overstate. BitMart didn’t publish nothing, it published excuses, and eventually a partial gesture, but never the real thing.
In BitMart’s own official statement, addressing user concern over its reserves directly, the exchange wrote: “We are actively advancing the necessary preparations and will publish our Proof of Reserves at an appropriate time, once security and risk control considerations are fully addressed.” That’s the company itself, in writing, treating a proper reserve audit as a future promise rather than something already delivered.
A separate official post goes a step further, admitting “we are working on the Merkle-tree proof-of-reserves,” and offering a partial list of hot wallet addresses instead, with the caveat built right into the disclosure: “these wallet addresses are provided for transparency purposes and represent only a portion of our total wallets.” A handful of visible addresses isn’t a Merkle tree. It’s a gesture toward one.
What makes this worse, not better, is that closer to the shutdown, reports surfaced citing a self-reported figure, “BitMart’s published Proof of Reserves shows a total of roughly $169 million in assets”, except a significant portion is composed of tokens with limited market depth, including SISC, TBC, and the exchange’s own native token, BMX, with USDT holdings reportedly a fraction of what was needed to process real withdrawals. A number without a real audit behind it isn’t transparency. It’s a headline dressed up to look like one.
What The Top 5 Built Instead: Verifiable Reserves
This is the section that matters most to me, because it’s where the gap actually lives. It’s not about who has more coins listed or flashier marketing. It’s about whether an exchange lets you check, cryptographically, that your money is actually there and does it repeatedly, not once as a PR moment.
Binance doesn’t ask for blind trust, its own reserves page spells out the logic plainly: “When a user deposits one Bitcoin, Binance’s reserves increase by at least one Bitcoin to ensure client funds are fully backed… we have zero debt in our capital structure and… an emergency fund (SAFU fund) for extreme cases.” It explains the underlying tool in a way I actually appreciate for its honesty: a Merkle Tree consolidates large amounts of data into a single hash, letting users verify specific contents were included.
OKX goes a step further on the privacy-preserving math. Its own page says: “We use a transparent Zero-knowledge proof algorithm, zk-STARK, to prove and verify all OKX account assets… without revealing any sensitive information about individual account balances.” And they’re not just talking about it once and moving on, their 22nd consecutive report confirms USD19.8 billion in primary assets backing customer funds, with more than 1.8 million customers having actually used the tool themselves. Twenty-two months in a row is a habit, not a headline.
Kraken, in its own blog, holds itself to what I’d call the stricter version of this promise: “We use a Merkle tree to combine individual balances into a single cryptographic hash… an independent accountancy firm then confirms that Kraken’s onchain holdings exceed total client balances… We include total client liabilities in every PoR.” That last line matters more than it sounds, plenty of exchanges show you what they hold and quietly skip what they owe. Kraken’s latest snapshot was attested as of December 31, 2025, covering BTC, ETH, SOL, USDC, USDT, XRP and ADA.
Bybit earns a mention here for what it survived, not just what it audited. Its own Hacken-audited report confirms: “Hacken’s team obtained the total assets of Bybit… conducted an extensive audit of the code used to generate the Merkle tree… and compared the output… against the liabilities report.” This is an exchange that took a massive hit in 2025 and still walked out solvent because the reserve discipline was already in place before the crisis, not scrambled together after.
Coinbase plays this differently, and I think that’s worth respecting rather than dismissing. Its own SEC filing leans on regulatory weight instead of crypto-native cryptography: “As a U.S. public company, we are required to undergo annual audits and quarterly reviews, which require that our independent registered public accounting firm reviews and audits our internal controls and reconciliation processes… we generally seek to hold no more than 2% of assets under custody in hot wallets at any given time.” And there’s a legal backstop most users don’t even realize exists: under UCC Article 8, customer assets are not property of Coinbase and not subject to claims of its general creditors. Different model, same underlying promise, you can check the receipts.
Final Thoughts
I keep coming back to this: BitMart didn’t fail to publish proof of reserves out of neglect. It said, repeatedly, that one was coming and never delivered the real version before the doors closed. Compare that to five exchanges that treat this as routine, published in their own words, on their own domains, month after month or audit after audit, and the difference stops being about volume or listings. It becomes a question of whether the receipts existed when they were actually needed. In this industry, that’s usually the only question that ends up mattering.
