Australian Regulator Sues Ex-Director of Crypto Exchange ACX for Mishandling Funds
Investigations have been ongoing since ACX Exchange collapsed in 2019.

What to know:
- Allan Guo, the former director of the closed down Blockchain Global, will face court proceedings in Australia.
- "ASIC’s allegations against Mr Guo relate to his dealings with ACX Exchange customer funds, statements made about those dealings and obligations to keep proper books and records," the regulator said.
Allan Guo, the former director of the closed down Blockchain Global, will face court proceedings in Australia over allegations that he mishandled customer funds of crypto exchange ACX, which was operated by Blockchain Global.
The Australian Securities and Investments Commission (ASIC) is bringing civil penalty proceedings in the Federal court against Guo and his involvement in the running of ACX Exchange, which collapsed in December 2019, leaving customers in the dark and unable to withdraw funds.
"ASIC’s allegations against Mr Guo relate to his dealings with ACX Exchange customer funds, statements made about those dealings and obligations to keep proper books and records," the regulator said in a post on Wednesday.
Investigations have been ongoing since Blockchain Global collapsed in 2019. Liquidators found in proceedings that occurred from 2022 that the company owed around $59 million to its creditors and close to $22.8 million of that money belonged to creditors from the ACX Exchange.
Guo reportedly left Australia in September 2024, after a travel restraint against him expired in August. The travel restraint was put in place in February last year when ASIC said it was investigating Guo and two other directors from Blockchain Global, Samuel Xue Lee and Zijang (Ryan) Xu regarding their involvement in the collapse of the ACX Exchange.

KuCoin Hits Record Market Share as 2025 Volumes Outpace Crypto Market

KuCoin captured a record share of centralised exchange volume in 2025, with more than $1.25tn traded as its volumes grew faster than the wider crypto market.
What to know:
- KuCoin recorded over $1.25 trillion in total trading volume in 2025, equivalent to an average of roughly $114 billion per month, marking its strongest year on record.
- This performance translated into an all-time high share of centralised exchange volume, as KuCoin’s activity expanded faster than aggregate CEX volumes, which slowed during periods of lower market volatility.
- Spot and derivatives volumes were evenly split, each exceeding $500 billion for the year, signalling broad-based usage rather than reliance on a single product line.
- Altcoins accounted for the majority of trading activity, reinforcing KuCoin’s role as a primary liquidity venue beyond BTC and ETH at a time when majors saw more muted turnover.
- Even as overall crypto volumes softened mid-year, KuCoin maintained elevated baseline activity, indicating structurally higher user engagement rather than short-lived volume spikes.
