WikiBit Exchange Exit Risk Ranking – Issue 13: BiFinance: An Exchange Officially “Hammered” by Hong Kong’s SFC—What Is There Left to Defend?

Introduction: An “Official Certification” from the Regulator Is More Fatal Than Any Negative Review　　In the previous 12 issues, we dug into HashKey (the compliance top student), HTX (a sanctions hotspot), UZX (a DAO penny stock), Phemex (the Morgan Stanley elite), Tapbit (the MSB sticker king), Coincheck (Japan‘s “immortal phoenix”), Deepcoin (the new outfit in El Salvador), Upbit (South Korea’s national exchange), Azbit (officially slapped down by the Seychelles FSA), FameEX (the three-country regulatory sticker collector), Bitvavo (Europe‘s compliance king), and CoinUp (personally “hammered” by He Yi)—and along the way, we’ve seen our fair share of regulatory problems.　　But todays subject takes things to a whole new level: BiFinance.　　Its résumé looks pretty impressive:　　“Top 50 globally on CMC,” “$3.1 billion in 24-hour trading volume,” “Completed Series A and Series B financing,” “Strategic investment from listed companies such as Donghao Asia and Dingyi Group,” “U.S. MSB registration,” and “A leader in the RWA sector.”　　Sounds like the standard résumé of a “star project,” right？　　But on the other side of the story:　　On July 31, 2026, Hong Kongs Securities and Futures Commission (SFC) placed BiFinance on its Alert List of Suspicious Virtual Asset Trading Platforms. The official designation states that BiFinance “is not licensed by the SFC

WikiBit Exchange Exit Scam Risk Ranking #12 — CoinUp: The Exchange Personally “Called Out” by Yi He — Would You Still Keep Your Money There?

Introduction: An Exchange Named by the “Crypto Industry Inspector”　　In the previous 11 editions, we investigated HashKey (the compliance top student), HTX (a sanctions hotspot), UZX (the DAO penny-stock case), Phemex (the “Morgan Stanley elite” narrative), Tapbit (the MSB registration king), Coincheck (Japan‘s crypto phoenix), Deepcoin (the El Salvador makeover), Upbit (South Korea’s national exchange), Azbit (the Seychelles FSA regulatory embarrassment), FameEX (the three-country license collector), and Bitvavo (Europes compliance champion).　　Each one had its own set of problems.　　Today, in the 12th edition, we are looking at one of the most explosive cases — CoinUp.　　This exchange has an impressive-sounding resume:　　“Founded in Silicon Valley in September 2021,”　　“Registered in the Cayman Islands,”　　“Operating centers in Singapore, Canada, and Hong Kong,”　　“Ranked No.29 globally in derivatives trading volume on CoinMarketCap,”　　“More than $12.98 billion in 24-hour derivatives volume,”　　“Over 15,000 daily active users,”　　“300+ spot trading pairs, 700+ spot markets, 100+ futures products,”　　“Daily trading volume reaching billions of dollars.”　　Sounds like the profile of a top-tier exchange, right？　　But on the other side of the story:　　Binance co-founder Yi He publicly accused its “operator” of impersonating others for fraud, and even Justin Sun was reportedly deceived by him; WikiBits assessment shows “questionable regulatory credentials” and “no valid regulatory information found”; numerous users complained

WikiBit Exchange Exit Scam Risk Ranking Issue #11 — Bitvavo: The “Compliance King” of Europe Powered by MiCA, Why Are Users Still Complaining?

Introduction: Finally, a “Serious Player”　　In the first 10 episodes, we investigated HashKey (Hong Kong licensed), HTX (sanctions hotspot), UZX (DAO penny-stock style exchange), Phemex (Wall Street elite background), Tapbit (MSB registration collector), Coincheck (Japan‘s “immortal phoenix”), Deepcoin (El Salvador’s new regulatory outfit), Upbit (South Koreas national exchange), Azbit (the Seychelles FSA officially calling it out), and FameEX (the three-country registration collector).　　Throughout the series, the number of red flags was overwhelming.　　But in Episode 11, we finally encounter a completely different type of exchange — Bitvavo.　　Compared with the previous cases, Bitvavos resume looks like a breath of fresh air:Founded in Amsterdam in 2018Registered with the Dutch Central Bank (DNB)Obtained an EU MiCAR license in 2025Ranked No.1 in European euro spot trading volume (44% market share)Quarterly independent Proof of Reserves (PoR) audits€7.55 billion theft insurance coverage€100,000 account protection　　Every item appears to follow the rhythm of “compliance.”　　However, on the other side of the story:　　Bitvavo has a Trustpilot score of 4.1/5 (“Great”), yet some users complain about:“Withdrawals delayed for 29 days”“Accounts frozen without clear explanations”“Customer support responses feel like AI-generated replies”　　So how can an exchange with one of Europes strongest compliance frameworks still receive user complaints？　　Today, we will break it down layer by layer.1.

Crypto September Financial Calendar: Regulatory Double Whammy + Rate-Hike Triple Play — A Preview of September’s “Crypto Bloodbath”

Bitcoin closed August with a gain of approximately 24% (Binance data). Even by bull-market standards, that is a top-tier monthly performance. As a result, the market went directly from deserted and lifeless trading conditions to a sudden return of bullish greed, with the Fear 40,000 | Estimated probability: ~25%　　If employment growth falls significantly short of expectations—or turns negative again—it would reinforce signs of a weakening labor market. Expectations for the Fed to maintain an accommodative stance would rise, potentially allowing Bitcoin to extend its rebound.　　Scenario 2: Data meets expectations　　New jobs: 50,000–70,000 | Estimated probability: ~55%　　If payroll growth lands within the consensus range of roughly 55,000–65,000, the “low hiring, low firing” environment would continue. The market would likely maintain its current rate-hike expectations—around 57%—and Bitcoin could experience short-term whipsaw volatility in both directions.　　Scenario 3: Data unexpectedly comes in strong　　New jobs 80,000 | Estimated probability: ~20%　　A stronger-than-expected employment report would further reinforce market pricing for a September Fed rate hike, potentially pushing Treasury yields higher and putting pressure on risk assets. Bitcoin could face short-term selling pressure.　　Of course, a series of preliminary indicators will be released before the nonfarm payrolls report:　　Tuesday: July JOLTS job openings　　Wednesday: August ADP employment report　　Thursday: Federal Reserve Beige

WikiBit Exchange Exit Risk Ranking Issue #10 — FameEX: Three License Stickers + 1.1 Rating, the “Emperor’s New Clothes” of the “World’s First Full-Stack Crypto Trading Platform”

WikiBit Crypto Market Weekly Outlook: BTC at a Crossroads — $85K Upside or $73K Downside?

1.Weekly Market Review: From “Dead Water” to a “Tsunami”　　Just 14 days ago, the entire market was still crying that “trading volume had fallen to the lowest level since 2019.” Then suddenly, Bitcoin exploded from $63,838 to $81,255.　　BTC gained 27% in 21 days, with a 20% surge in just three days — the strongest three-day rally since 2023.　　Ethereum was not left behind, rising more than 30% last week. The entire market instantly switched from a “ghost town atmosphere” to a “bull market celebration mode.”　　However, the party did not last long.　　After hitting $81,255, BTC quickly pulled back by $2,700, falling toward the $78,500 area. As of the Asian trading session on August 28, BTC was fluctuating around $79,800.　　The daily candlestick formed a typical long upper shadow, a textbook example of a sharp rally followed by a rejection.2.Why Did BTC Surge？ Three Words: Short Squeeze! Short Squeeze! Short Squeeze!　　The main driver behind this rally was not retail FOMO.　　Instead, it was a combination of U.S. Treasury buyback operations and a forced liquidation cascade of approximately $4 billion in short positions.　　Short sellers watched helplessly as BTC climbed from $64K all the way to $81K. They were forced to close positions at higher prices, which in

WikiBit Exchange Exit Risk Ranking Issue #8 — Azbit: Backed by Roger Ver, Publicly Called Out by Seychelles FSA — An Offshore Casino Riding on a “Celebrity Endorsement”

Introduction: An Exchange That “Lives More in Legends Than Reality”　　In previous episodes, we investigated HashKey (the compliance role model), HTX (the sanctions hotspot), UZX (the DAO penny stock), Phemex (the Wall Street elite team), Tapbit (the MSB license sticker king), Coincheck (Japan‘s survivor), Deepcoin (El Salvador’s new regulatory disguise), and Upbit (South Koreas national exchange).　　Todays subject is another “offshore registration specialist” — Azbit.　　Its resume looks surprisingly impressive:“Bitcoin.com founder Roger Ver serves as an advisor”“Founded in 2018, headquartered in Estonia”“Listed more than 400 projects”“Offers spot trading, margin trading, futures, staking, savings, IEO, and other one-stop crypto services”　　Sounds like a full-featured major exchange, right？　　But on the other side of the story — this offshore exchange, whose corporate entity is registered in Seychelles, was publicly warned by the Seychelles Financial Services Authority (FSA) on August 7, 2026.　　The regulator stated that Azbit:“has never obtained any authorization”the company was in “not good standing” due to failure to pay annual fees　　Meanwhile, after years of operation, Azbit has accumulated negative reports involving withdrawal disputes, promotional traps, and regulatory uncertainty.　　So how did an exchange endorsed by the “Bitcoin Jesus” become the target of a public regulatory warning？　　Today, we will break it down layer by layer.1.

WikiBit Exchange Exit Scam Risk Ranking – Episode 6: Coincheck: Hacked for $530 Million, Acquired by a Financial Giant, Listed on Nasdaq — The Ice and Fire Saga of Japan’s “National Exchange”

Introduction: An Exchange That Has “Died Once”　　In previous episodes, we investigated HashKey (the compliance top student), HTX (the sanctions-hit exchange), UZX (the DAO penny-stock project), Phemex (the Morgan Stanley elite team), Tapbit (the “MSB license sticker king”), and Deepcoin (the “El Salvador new outfit”).　　Todays subject is probably the most dramatic one in the entire series — Coincheck.　　In January 2018, Coincheck suffered the largest cryptocurrency theft in history at the time: hackers stole $530 million worth of NEM tokens.　　For most exchanges, such a disaster would likely have ended with a shutdown or even an exit scam.　　But Coincheck survived.　　It accepted corrective measures imposed by Japan‘s Financial Services Agency (FSA), was acquired by listed company Monex Group, went public on Nasdaq in 2023, and in 2026 obtained Japan’s first stablecoin-related license.　　An exchange that had “died once” somehow came back as the “immortal phoenix” of Japans crypto market.　　However, on the other side of the story:Trustpilot rating: 1.7/5In April 2025, Coinchecks official X account was hacked, causing a platform-wide disruptionUsers complained about account freezes and withdrawal problems　　Why does an exchange that was acquired by a publicly listed company and listed on Nasdaq still get called a “SCAM” by some users？　　Today, we will break it down

Bitcoin Breaks Above $80,000 Again After 100 Days, While the Fed Makes Successive Moves: “Bull Market Returns Fast” OR “Dead Cat Bounce, Run While You Can”?

Introduction　　After exactly 100 days, Bitcoin reclaimed the $80,000 level on August 24, and surged further to $81,272 on August 25 (according to Binance data) before pulling back.　　Following its retreat from the yearly high, Bitcoin spent nearly three months moving sideways and building a bottom within a narrow $57,000–$68,000 range. Then, within just a few trading days, it exploded higher, posting a monthly gain of more than 28%.　　However, just three weeks earlier, in early August, Bitcoin was still hovering around the $64,000–$66,000 range. The 30-day average of active addresses once fell to 609,000, approaching levels seen during the 2018 bear market. Within only a few days, market sentiment shifted from “fear” to “extreme greed” — the Crypto Fear 　　Volatility dropped to the lowest level of the year;　　The market entered a state of “bulls and bears locked in battle, while retail investors stayed on the sidelines.”　　However, two important undercurrents emerged during this consolidation phase:　　1. OTC Trading Activity Increased Significantly　　Long-term investors, including early Bitcoin whales and institutions linked to publicly listed companies, continued accumulating spot Bitcoin around the $60,000 level, quietly rebuilding positions.　　2. Short Positions Continued to Build in Derivative Markets　　A growing number of traders bet that Bitcoin would break below the lower
