Katerini's AI club allegedly recruited members for an $8 million Greek crypto pyramid
Greek police have arrested 17 people, including servicemen, over an alleged crypto pyramid they say took about $8 million from roughly 10,000 investors. Those totals are untested police estimates, and the deposits investigators can document so far are far smaller.
The Investor · Invest desk
What happened
- The Athens daily To Vima reports that recruiting ran through a local civic group, whose Katerini leader, the 44-year-old head of the Association of Artificial Intelligence Friends, was remanded in custody.
- Members could join from €800 while so-called VIP investors were asked for €5,000, and police say the unauthorised platform promised to double their money within 50 days.
- ERT, citing reporter Giorgos Gerafentis, said members were paid bonuses for bringing in new participants under a hierarchy controlled by the alleged leaders.
- Searches of five offices, nine homes and other premises turned up cash, 32 mobile phones, 28 computers, 15 tablets and a money-counting machine.
- The case began in July with two anonymous complaints filed through gov.gr, the Greek government's digital services portal, to Katerini crime investigators.
Why it matters
- What doesn't add up contradiction Decrypt's account, drawn from To Vima, has two military suspects, while ERT counts nine military personnel among the 17 arrested, so how large the armed forces' role in the network was is still unsettled.
- What it costs cost The €295,090 in seized cash equals about 15% of the €2 million attributed to Katerini members alone, so even returning all of it would repay a small part of one town's deposits.
- Who's exposed exposure Because recruits were paid to sign up others, some of the 10,000 counted as investors were also recruiters, and prosecutors will have to separate victims from participants when the case is charged.

Divide the police estimate of $8 million by 10,000 investors and the average stake is $800 [21], close in nominal terms to the €800 entry ticket in a scheme that also sold a €5,000 VIP tier [14]. On those numbers, either most members paid the minimum once or the headcount includes people who paid very little. Katerini, the one town with its own figures, runs higher. Investigators estimate 1,842 members there put in around €2 million [20], about €1,086 each [22]. If every Katerini member bought exactly one of the two tiers, roughly one in fifteen paid for VIP [26].
Doubling every 50 days, the offer police describe [9], compounds to about 158 times the stake over a year if each payout is reinvested [27]. Prosecutors say the organisation pushed investors into cryptocurrencies through a platform it controlled and operated as a pyramid scheme [3].
Katerini also matters because the club was based there. Its 1,842 members are about 18% of the national count [28]. Investigators believe the Larissa serviceman picked up the method from a contact he met while travelling overseas [19]. Six others from the first seven arrested were released under restrictive conditions on bail of €15,000 to €20,000, according to the public broadcaster ERT [13]. The October 2 police statement, as crypto.news reported it, refers to company structures and an online platform used to present the investments as legitimate [7]. That account does not mention the club.
Police can document far less than they estimate. They have identified 18 victims with combined deposits of €55,970 [12], an average of about €3,109 [23]. Those 18 are 0.18% of the claimed membership [24]. Their average sits between the two tiers, so at least some of the named victims paid more than the entry price.
A charging document could cut the 10,000 down toward the depositors police can name. The club could also turn out to be just one branch's recruiting channel in a network ERT placed in Katerini, Thessaloniki, Larissa, Patras and an island in the Dodecanese [16]. In my view, the Katerini branch is the best-documented part of the case and the national totals are the weakest. A charge sheet confirming something near $8 million across thousands of named depositors would prove that wrong.
What to watch
- The investigating judge's charging document in Katerini, and whether it keeps the 10,000 headcount and $8 million total or replaces them with named depositors and traced sums.
- Whether the nine additional suspects in ERT's account of the case file, including another member of the armed forces, are charged.
