New York Man and Firm Ordered to Pay $228M Following Ponzi Scheme
A federal judge in Manhattan has mandated that Eddy Alexandre and his company, EminiFX, reimburse over $228 million after the Commodity Futures Trading Commission (CFTC) charged them with orchestrating a Ponzi scheme involving forex and cryptocurrency trading. The ruling confirmed that Alexandre misappropriated substantial investor funds, with court documents indicating that victims collectively invested over $262 million within just eight months. During this period, EminiFX incurred losses exceeding $49 million, largely due to Alexandre’s diversion of investor funds into personal accounts. The judgment entails more than $228.6 million in restitution and an additional $15 million payment from Alexandre for improper gains, who is now serving a nine-year sentence for related offenses.
Google Clarifies Play Store Policy: Non-Custodial Wallets Not Prohibited
Recent updates to Google’s policy suggested that non-custodial crypto wallets could be barred from the Play Store, a notion that triggered considerable backlash from users concerned about the implications for widely-utilized self-custody solutions. In response, Google clarified that its policy specifically targets custodial wallets, ensuring that non-custodial options remain permissible. This clarification outlines that developers in the U.S. must register as a money services business or operate under state-chartered banks to comply with local laws.
Coinbase Suffers $300K Loss Due to Smart Contract Misconfiguration
Coinbase has reported a loss of approximately $300,000 owing to misconfigured token approval processes through the 0x Project’s “swapper” contract, which is intended for token swaps but not approval transactions. The flaw was highlighted by security researcher “deeberiroz” from Venn Network, indicating that malicious actors exploited this oversight, targeting tokens such as Amp and DEXTools. The incident, attributed to a recent change in corporate wallet setup, has since led Coinbase to revoke token allowances to mitigate further risks.
GMX Initiates $44M Repayment to Users Affected by Arbitrum Exploit
In response to a July exploit that impacted its funds pool on Arbitrum, decentralized exchange GMX is initiating a $44 million compensation distribution to affected users. The recovery stems from a negotiation with the attacker, and combines retrieved funds with an injection from GMX’s treasury. This exploit exploited a reentrancy vulnerability permitting excessive fund withdrawals. As part of the reparative measures, eligible users will be rewarded with GLV tokens along with incentives for retaining them over a set duration.
BtcTurk Suspends Crypto Transactions Following $48M in Suspicious Transfers
Turkey’s BtcTurk has temporarily suspended all crypto deposits and withdrawals after a blockchain firm flagged roughly $48 million in suspicious transactions. The exchange attributed the suspension to a “technical issue” but clarified that services related to the Turkish lira remain unaffected. As funds were observed moving rapidly through multiple networks before consolidation, this incident highlights ongoing concerns regarding transaction monitoring within the crypto space.
U.S. Banking Associations Urge Senate to Tighten Stablecoin Regulations
In a concerted effort, major U.S. banking associations are urging lawmakers to amend the recently enacted Guiding and Establishing National Innovation for U.S. Stablecoins Act, citing potential loopholes that may destabilize financial integrity.

Federal Reserve Concludes Special Oversight for Crypto Activities
