Recruitment grew around a cryptocurrency that did not work as advertised
OneCoin began in 2014, based in Sofia, Bulgaria, and spread through a global multi-level marketing network. Members were paid for recruiting buyers of cryptocurrency packages. Co-founder Karl Sebastian Greenwood pleaded guilty to wire-fraud and money-laundering offences on 16 December 2022. His plea and the accompanying case record describe a deliberate fraud, rather than an otherwise legitimate cryptocurrency that simply fell in price. DOJ announcement of Greenwood’s guilty plea.
On 12 September 2023, Greenwood received a 20-year prison sentence. The sentencing announcement described more than $4 billion invested by millions of victims and approximately $300 million earned by Greenwood through the scheme. Those figures concern the case record and identified proceeds; they should not be presented as a current total of money recovered or returned to victims. DOJ sentencing announcement.

The promised mining and the actual accounting were different things
The plea record describes fabricated mining claims and internal control over the displayed coin price. It also describes coins allocated to members that were absent even from the system represented as OneCoin’s private blockchain. The sentencing record similarly explains that the claimed mining pools and mining computers did not exist as advertised. These were false representations about how the product was created and recorded, not merely arguments about whether a private network was sufficiently decentralised.
That distinction prevents a common analytical mistake. A system can be centrally operated and still keep real, auditable records. Conversely, calling a database a blockchain does not demonstrate that its transactions, issuance and ownership rules match the sales pitch. An investigator needs to identify what the system actually does, who can change its records and which claims a participant can check independently. A diagram of interconnected computers is not evidence that those computers operate the advertised protocol.
A rising number on a dashboard is not a market price
In a genuine market transaction, a quoted value must be distinguished from an executable price and from proceeds that can actually be withdrawn. If a platform declares that an account owns 1,000 units worth 10 each, the multiplication is easy. The hard questions are whether an independent buyer will pay that price, whether a trade can settle and whether the owner can remove the proceeds without buying another package. All 3 questions can remain unanswered while the dashboard shows a large profit.
This is why a screenshot of a growing account cannot establish investment performance. The display, the transaction history behind it and the external assets available for redemption must be examined separately. The lesson applies to fake investment platforms as well as to cryptocurrency packages. It does not mean that every account-based product is fraudulent; it means that the operator’s own display cannot serve as independent verification of the operator’s claim.
Follow recruitment income separately from investment returns
A recruitment reward is income for the recruiter, but it does not demonstrate that the underlying investment generated a return. Mixing those flows can make a sales network look like a successful investment strategy. An assessment should separate money from new package purchases, commissions paid to recruiters, withdrawals by existing members and revenue from genuine activity outside the recruitment system. The source-of-returns guide develops this distinction.
The same separation matters when evaluating promoters. Payment records, compensation terms and the claims a person actually made are more informative than photographs from a stage. Attendance at an event alone does not establish knowledge of a fraud. A documented commission and a misleading sales claim are different evidence items and should be recorded as such. That keeps responsibility tied to conduct rather than to guilt by association.
Use dated records for legal outcomes and victim recovery
Greenwood’s guilty plea and sentence are established events in his case. They should not be used to invent a conviction, location or current status for another person. Likewise, forfeiture and victim repayment are separate processes. For later developments, the wiki has a dedicated entry on the 2026 victim-compensation process. Keeping that process separate makes it possible to update repayment information without rewriting the history of the original deception.
