Coinsuper Crypto Exchange Review: A Defunct Platform and How to Avoid Exit Scams

There’s no such thing as a good review of Coinsuper - because the exchange doesn’t operate anymore. If you’re looking at Coinsuper right now, you’re probably seeing an old blog post, a forgotten forum thread, or worse - a fake website trying to steal your money. Coinsuper was once a mid-sized crypto exchange based in Hong Kong, but by late 2021, it stopped letting users withdraw their funds. Then it vanished. Today, in 2025, it’s a textbook example of an exit scam.

What Happened to Coinsuper?

In November 2021, users started noticing something strange: they couldn’t pull their crypto out of Coinsuper. Not a delay. Not a technical glitch. A full block. No matter how many times they clicked “withdraw,” the transaction would hang forever. Some tried contacting support. No replies. Others posted on Reddit and BitcoinTalk. The same story kept popping up: $5,000 locked. $12,000 gone. $55,000 total in verified losses across dozens of users.

By February 2022, the website’s live chat was offline. Emails went unanswered. The official blog stopped updating. By June 2022, the domain coinsuper.com expired. Today, if you type it in, you get a blank hosting page - the digital equivalent of an abandoned building with boarded-up windows.

This wasn’t a crash. It was a planned collapse. The pattern matches every known exit scam: grow quickly, attract users with low fees and easy signups, then cut off withdrawals and disappear. Bloomberg reported at the time that internal communications showed management knew about the withdrawal freeze weeks before users did. No warning. No apology. Just silence.

Why People Trusted Coinsuper (Before It Vanished)

Before it turned toxic, Coinsuper looked convincing. It supported over 100 trading pairs - BTC, ETH, USDT, and a bunch of smaller altcoins. Its trading fees were low: 0.20% for takers, 0.14% for makers. That was competitive back in 2020-2021. It accepted fiat deposits in USD, EUR, and HKD - something few Asian exchanges did at the time. It had KYC checks, which made it feel “legit.”

It even claimed a daily trading volume of $11 million. That put it around #47 globally in late 2021. Not huge, but enough to seem like a real player. And Hong Kong? That sounded safe. People assumed if it was based there, it had to follow rules.

But here’s the problem: Hong Kong didn’t require exchanges to prove they held users’ funds. No mandatory proof-of-reserves. No public audits. No regulatory license needed until April 2022 - after Coinsuper had already collapsed. That loophole was exactly what they used.

How Coinsuper Compared to Real Exchanges

Compare Coinsuper to Kraken, Coinbase, or even Bybit - exchanges that still operate today. They all do three things Coinsuper never did:

• Publicly publish proof-of-reserves audits
• Use multi-signature cold storage with third-party verification
• Have clear, licensed regulatory status

Coinsuper had none of these. Its withdrawal fees were also higher than average: 0.001 BTC per withdrawal. Most exchanges charged around 0.00057 BTC. That’s 75% more. Why? Probably because they knew users wouldn’t notice - until it was too late.

And here’s the kicker: while Coinsuper was busy locking funds, competitors like Kraken were maintaining 99.9%+ withdrawal success rates. CoinGecko and CoinMarketCap removed Coinsuper from their rankings by early 2022. No one in the industry still lists it as active.

User Reviews: The Real Story

Don’t trust the old marketing materials. Look at what real users said.

Trustpilot has 147 reviews for Coinsuper as of October 2025. The average rating? 1.2 out of 5. Ninety-two percent of those reviews mention “blocked withdrawals.” One user wrote: “I deposited $8,500 in ETH. Now it’s gone. No response from support. No refund. I lost everything.” That thread on Reddit got 287 upvotes and 43 similar stories.

The BitcoinTalk “Scam Alert” forum has a sticky thread titled “Coinsuper - Confirmed Exit Scam.” It lists 189 verified loss reports. The total? Around $55,000. That’s just what people reported. How many didn’t speak up? We’ll never know.

The Hong Kong Police Force recorded 37 formal complaints between December 2021 and June 2022. No arrests. No recovery. Just paperwork collecting dust.

Is There Any Way to Get Your Money Back?

Short answer: No.

Legal experts from Forbes confirmed in September 2025 that the statute of limitations for financial fraud cases involving platforms like Coinsuper expired in most countries by late 2024. That means even if you wanted to sue, you’re out of time.

Some users tried hiring lawyers. Others pooled funds for class-action suits. None got results. The company’s servers are gone. The team? Disappeared. No LinkedIn profiles. No phone numbers. No public statements.

Chainalysis classified Coinsuper as a “confirmed exit scam” in its 2025 Market Integrity Report. That’s the industry’s official label for exchanges that steal user funds and vanish. Coinsuper sits alongside other dead platforms like BitKRX and CoinTrade.

What You Should Do Instead

If you’re looking for a crypto exchange in 2025, don’t look at old names. Look at what’s alive, audited, and regulated.

Here’s what to check before depositing money:

• Is the exchange licensed in a major jurisdiction? (e.g., U.S., EU, Japan, Singapore)
• Does it publish monthly proof-of-reserves from a reputable auditor? (e.g., BDO, Armanino)
• Are withdrawal fees below 0.0006 BTC for Bitcoin? (Industry standard)
• Is it listed on CoinGecko or CoinMarketCap with active trading volume?
• Are there recent user reviews mentioning successful withdrawals?

Top picks in 2025 include Kraken (5.0/5 on NerdWallet), Coinbase (4.9/5), and Bybit (99.95% uptime, 24/7 support). All have clear regulatory status. All allow withdrawals. All have public audits.

Why This Matters Beyond Coinsuper

Coinsuper isn’t just a bad exchange - it’s a warning sign. It shows how easy it is for unregulated platforms to trick people into trusting them. The same tactics are being used today by new platforms pretending to be “next-gen” or “Hong Kong-based” or “low-fee.”

Hong Kong tightened its rules after Coinsuper collapsed. Now, all exchanges must get a license and prove they hold users’ assets. That’s progress. But new scams pop up every month - often with new names, new websites, and the same old promises.

The lesson? Never trust an exchange just because it looks professional. Always verify what’s behind the website.

Final Verdict

Coinsuper is dead. It’s not suspended. It’s not undergoing maintenance. It’s gone. And anyone still promoting it as a viable option is either misinformed or trying to sell you something.

If you lost money to Coinsuper, you’re not alone - but you’re out of options. The only thing you can do now is learn from it. Never again deposit funds into an exchange without checking its audit history, regulatory status, and recent user withdrawal reports.

Crypto is risky enough without adding scams to the mix. Stick to platforms that are open, audited, and accountable. Your funds - and your peace of mind - depend on it.
