According to Gold Finance, a consumer warning issued by the Washington State Department of Financial Institution (DFI) Securities Department said that an investor learned about a encryption trading platform called Ethfinance through an unsolicited LinkedIn connection, and transferred a total of $310,000 from its Decentralized Finance Wallet to the platform. When he tried to withdraw part of the initial principal and profits, the investor was told that more long funds needed to be added to complete the "smart contracts" and then the funds were withdrawn.

DFI said that investors did not remit any additional funds. Investors are unable to withdraw any funds from their accounts and their accounts have been locked. The case appears to be a 'prepaid fraud case', but the charges have not been confirmed. The platform has also been mentioned in previous complaints, with a resident of California reporting that they encountered a stranger online who offered to teach them how to make money through trading cryptocurrency options, resulting in a loss of over $165,000.
