Green United LLC — Utah Founders Sold $18 Million in Fake Mining Boxes That Mined Bitcoin for Themselves
Summary
Between April 2018 and at least December 2022, Utah-based Green United LLC and its two principals — founder Wright W. Thurston and lead promoter Kristoffer A. Krohn — raised at least $18 million from retail investors by selling devices they called "Green Boxes" and accompanying software subscriptions called "Green Nodes." Investors were told the hardware would mine a proprietary cryptocurrency called GREEN on a purpose-built "Green Blockchain," with GREEN's value expected to increase as the company developed what it described as a public global decentralized power grid. None of that infrastructure existed. According to a complaint filed by the Securities and Exchange Commission in the District of Utah on March 3, 2023, the Green Boxes were commercially available S9 Antminers that Thurston purchased and used to mine Bitcoin for his own benefit; the bitcoin produced was never distributed to investors. The GREEN token itself was not created until several months after sales began, and the returns investors received came from pre-mined token distributions staged by Thurston to simulate active mining.
Green United deployed a multilevel marketing structure in which Krohn and affiliated promoters earned commissions for recruiting new buyers. Investors were promised monthly returns of forty to fifty percent, framed as proceeds from an active mining operation. No secondary market for GREEN tokens existed for more than two years after sales began; when one eventually formed, the token traded at a fraction of its promoted value. Apparent positive performance among early recipients suppressed skepticism and kept new capital entering through 2022.
The SEC filed its civil complaint on March 3, 2023, charging the defendants with selling unregistered securities under Sections 5(a) and 5(c) of the Securities Act and with fraud under Section 17(a) and Exchange Act Section 10(b)/Rule 10b-5. After defendants moved to dismiss, Judge Ann Marie McIff Allen ruled on September 23, 2024 that Green Boxes were sufficiently alleged to be investment contracts under Howey and that the fraud claims would proceed to trial. As of this dossier's filing date, no trial date has been set and no criminal charges have been filed.
Timeline
The Product They Built: A Token Looking for a Blockchain
Thurston established his sales premise before any supporting infrastructure existed: $3,000 per Green Box, forty to fifty percent monthly returns, paid in GREEN tokens that would appreciate as the company built a global decentralized power grid. Neither the token nor its blockchain existed when sales opened in April 2018. Thurston created GREEN several months into the fundraising period, deploying it on Ethereum rather than on any proprietary chain. The "Green Blockchain" — whose future development was supposed to underpin token value — was never built at any stage.
What investors purchased was, in the SEC's framing, a passive investment in a common enterprise whose returns depended entirely on Thurston's managerial decisions, not on any hardware the investor could monitor or verify. The Green Nodes — software subscriptions sold alongside the boxes — completed the product line. Described as software running on the Green Blockchain and generating GREEN through its operation, they were in reality basic packages that performed no mining function. GREEN tokens credited to Node holders, like those credited to Box holders, came from Thurston's pre-mined supply. Both product tiers shared the same underlying lie: that a blockchain existed and the hardware was working.
How Forty Percent Monthly Returns Are Paid When No Mining Occurs
Investors who received GREEN tokens during the early period saw nominal positive returns — a characteristic feature of pre-mined-token distribution fraud. Because Thurston controlled the supply, distributions could be timed and sized to match the promised return schedule without any computational work. The simulation was not contingent on mining; it was an accounting entry against the operator's token reserve.
Maintaining it required two conditions: a continuing supply of pre-mined GREEN, and a secondary market thin enough that investors would not liquidate in volume. No exchange listing existed for more than two years after sales began, denying investors any independent price signal. When trading eventually began in fall 2020, GREEN opened below its promoted initial value of $0.02 and settled near $0.004 — an eighty percent discount to expectations.
The S9 Antminers Thurston purchased with investor proceeds were not idle; they mined Bitcoin actively. That bitcoin was real, quantifiable, and deposited into accounts Thurston controlled — none of it reached investors. The scheme therefore ran two parallel operations: a pre-mined token distribution that simulated GREEN returns, and a genuine bitcoin mining business whose revenues flowed exclusively to the founder. Investors subsidized the latter while receiving a token of declining value in exchange.
The MLM Distribution Network and Krohn's Prior Record
Kristoffer Krohn's role in Green United was structural. An experienced multilevel marketing promoter, Krohn built a layered commission network in which recruiters brought in investors and earned fees at each level, creating strong incentives to suppress concerns and maximize enrollment speed. More than a decade before Green United, Krohn had faced SEC enforcement action for violations connected to a real estate investment program — a prior record that, the complaint implies, should have precluded him from serving as lead promoter of another unregistered offering.
Promoters recruited through existing social networks — family, friends, church communities — deploying the relationship-trust dynamics characteristic of affinity fraud. Investors enrolled through a known contact were less likely to conduct due diligence or attribute early negative signals to fraud rather than market conditions.
The Five Factors
Aftermath
As of the filing date of this dossier, SEC v. Green United, LLC (Case No. 2:2023cv00159, D. Utah) remains in active pre-trial proceedings. Judge Ann Marie McIff Allen's September 2024 ruling that Green Boxes constitute investment contracts under Howey was a significant procedural victory for the SEC and established a judicial record treating physical mining hardware sold with hosting agreements and return promises as securities — a classification with implications well beyond Green United's specific facts.
No criminal charges have been publicly announced. Krohn's prior SEC enforcement history did not prevent him from serving as promoter; it may affect any eventual civil penalty calculation. The approximately $18 million raised has not been subject to a court-ordered recovery mechanism as of this date. The SEC seeks permanent injunctions, disgorgement of ill-gotten gains plus prejudgment interest, and civil penalties.
The case is notable for its geographic profile: Utah has been a recurring site for affinity-based cryptocurrency and MLM fraud, and Green United's distribution network drew on the same close-knit social trust structures that characterize the pattern. The SEC's Salt Lake Regional Office, which brought the case, has developed significant enforcement experience with crypto-adjacent MLM structures, and the September 2024 Howey ruling is expected to inform its posture toward similar offerings.
Lessons
- Cloud mining hardware sold with hosting agreements and return promises may constitute investment contracts subject to securities registration requirements regardless of how the product is labeled; investors should treat the absence of SEC registration as a material red flag, not an administrative technicality.
- When a cloud mining operator creates its own proprietary token and distributes pre-mined supply as "returns," investors have no independent means of verifying whether distributions reflect actual mining output or a controlled release from a pre-existing supply; on-chain verification of mining wallet activity is the only reliable check.
- The absence of a secondary market for a token does not indicate that the token has no price — it indicates that investors have no independent price discovery mechanism, which benefits the operator and harms the investor; demand a market, or treat the stated value as entirely unverifiable.
- MLM distribution structures in investment offerings create a class of financially incentivized promoters whose interests are structurally misaligned with investor protection; commission-based recruitment rewards suppression of doubt and penalizes honest disclosure.
- A promoter's prior SEC enforcement history for similar conduct in adjacent industries is publicly searchable; investors and co-operators should verify the regulatory background of every named promoter before committing capital to any offering structured around that person's network.
