The co-founder of the crypto platform Forsage, Olena Oblamska, pleaded not guilty to charges of conspiracy to commit wire fraud after being extradited from Thailand to the United States. Forsage launched in January 2020, marketing itself to retail investors worldwide as a smart contract-based DApp investment platform. The U.S. Department of Justice accused the platform of using smart contracts on Ethereum, Tron, and BNB Chain to automatically redirect funds from new participants to early investors, constituting a Ponzi and pyramid scheme.Blockchain analysis shows that over 80% of Forsage investors received less cryptocurrency than they deposited, and over 50% received no returns at all. The scam defrauded victims from the U.S., Europe, Asia, and Latin America of approximately $340 million. The U.S. Securities and Exchange Commission had previously filed a civil lawsuit against those involved in August 2022.

U.S. prosecutors also accused him of using some of the funds to purchase Florida properties worth a total of $14.5 million, as well as for hosting lavish events and trips. Delgado is currently out on bail, and if convicted on all charges, he could face up to 30 years in federal prison.

ZachXBT warns that such scams primarily target ordinary retail investors, and victims should report to local police in a timely manner.

According to Politico, Poland's major cryptocurrency exchange Zondacrypto is facing a serious fraud investigation. Its former CEO went missing in 2022, taking with him the private keys to a cold wallet containing 4,500 bitcoins (currently worth over $340 million). The current CEO has admitted to being unable to access the wallet and has recently been reported to have fled to Israel. Prosecutors estimate potential losses for customers to be around $97 million.On-chain data shows that the bitcoin balance in the platform's hot wallet has plummeted by 99.7% since mid-2024, with users generally reporting difficulties in withdrawing funds. Polish Prime Minister Tusk estimates that up to 30,000 users may be affected.Tusk publicly accused the platform of being funded by Russian-linked money, used to finance opposition lawmakers to obstruct Poland's cryptocurrency regulatory legislation. He bluntly stated that this is a "Polish version of a Ponzi scheme" and criticized the president for vetoing the localization of the EU MiCA framework twice, making Poland a "paradise for scammers."The platform's board stated that they failed to obtain "verifiable information" from the missing CEO and have collectively resigned. The founder has been missing since 2022, and the previously mentioned "suspect kidnapping allegations" case is still under investigation. This incident is expected to prompt Poland and the EU to strengthen regulatory scrutiny of cryptocurrency exchanges.
