The strength of a fraud complaint is decided almost entirely by what can be documented, and documentation degrades fast. Fraudulent platforms are taken offline, chat histories are deleted from the operators side, and telephone numbers are abandoned. What exists on your own devices is often the only surviving record of a scheme that involved hundreds of people.
Financial records. Every transfer, with date, amount, beneficiary name, IBAN or wallet address, and the reference used. Bank statements rather than screenshots of a banking app, because a statement is a document the court can work with. If you paid by card, the card statement lines matter separately, since card networks have their own dispute routes with short deadlines.
The platform itself. Screenshots of your account dashboard showing the supposed balance, the trading history it displayed, and any withdrawal request you submitted together with the response. Save the full page including the web address, not a cropped image of a number. Where you still have login access, take these today.
The people. Names, telephone numbers, email addresses and messaging handles of everyone who contacted you, including the account manager, the supposed compliance department and any senior figure introduced later to reassure you. Export whole conversations rather than selected messages. The ordinary early conversations matter as much as the ones about money, because they establish how the confidence was built.
The paperwork they sent you. Contracts, terms, certificates, invoices, tax notices, licence documents. These are usually forged and their falsity is itself evidence. Keep them exactly as received, including the original email with its headers where possible.
Do not edit, annotate or reorganise any of it. Send us what you have in the state you have it, even if it feels fragmentary or embarrassing. Cases have been built on less than clients expected, and the material that victims assume is worthless, such as the small talk before the first deposit, is frequently what establishes the deception.
