The Ruling
On September 6, 2019, a fierce policy debate erupted across Washington following explosive testimony before a US Senate subcommittee earlier that week. David Murray, vice president at the Financial Integrity Network — a Washington, DC-based consulting firm specializing in illicit finance — called on the federal government to expand the Bank Secrecy Act (BSA) to cover cryptocurrency miners and virtual asset transaction validators. The proposal, if enacted, would fundamentally reshape how the United States regulates the Bitcoin network and could set a precedent with global ramifications.
Murray’s testimony, delivered on September 3 before the Senate Banking Subcommittee, urged lawmakers to broaden the BSA’s definition of a “financial institution” to include entities that the current regulatory framework deliberately excludes: the miners who validate transactions on proof-of-work blockchains like Bitcoin. His argument centered on the claim that “virtual assets are vulnerable to illicit finance because they offer rapid and irrevocable settlement and the potential for anonymity.”
At the time of the hearing, Bitcoin traded at approximately $10,353, having experienced significant volatility throughout 2019 after reaching highs near $13,800 in late June. The cryptocurrency market cap stood at roughly $220 billion, with Bitcoin commanding a dominant 70.8% share of the total market.
International Precedents
The push to regulate miners under anti-money laundering frameworks represented a sharp departure from established international norms. The Financial Action Task Force (FATF), the Paris-based intergovernmental body responsible for setting global anti-money laundering standards, had explicitly chosen to focus its regulatory attention on cryptocurrency exchanges rather than miners. This decision reflected a pragmatic recognition that miners operate differently from traditional financial intermediaries.
Under existing BSA rules, cryptocurrency exchanges and crypto-asset storage providers were already classified as money services businesses and required to collect user information and file suspicious activity reports for transactions exceeding $5,000. However, Murray argued that these measures were insufficient, as other “important participants in blockchain systems” remained outside the law’s scope.
The timing of the proposal was notable. In June 2019, FATF had issued its updated guidance requiring Virtual Asset Service Providers (VASPs) to implement the so-called “travel rule,” mandating that they share customer information during transfers. The global regulatory community was already grappling with how to apply traditional financial surveillance tools to decentralized networks — and Murray’s proposal to extend oversight to miners represented one of the most aggressive interpretations yet.
Enforcement Reality
Peter Van Valkenburgh, director of research at Coin Center, a blockchain policy advocacy group in Washington, DC, pushed back forcefully against the proposal. He argued that regulating Bitcoin miners as money services businesses would “basically make the technology nonviable” in the United States. His critique exposed the fundamental tension between traditional regulatory paradigms and decentralized network architectures.
Van Valkenburgh made several critical points that resonated across the crypto policy community. First, he noted that miners do not have customers in any traditional sense — they simply run the Bitcoin protocol software and compete to validate blocks in hopes of earning the block reward. “They have no idea who has requested transactions on the blockchain,” he explained, adding that miners are “just running the protocol” in hope of a reward. Forcing them to conduct know-your-customer checks or file suspicious activity reports would be functionally impossible.
Second, he highlighted the jurisdictional nightmare of attempting to regulate a global, pseudonymous network. Given Bitcoin’s decentralized nature, it would be extraordinarily difficult to identify and locate all miners, many of whom could simply relocate to jurisdictions with less stringent requirements. The result would be a regulatory framework that punishes American miners while doing nothing to actually curb illicit finance on the network.
Third, Van Valkenburgh pointed out that the US Treasury Department had long possessed the authority to broaden the BSA’s definition of a financial institution to include cryptocurrency miners but had “explicitly chosen not to.” This deliberate restraint suggested that the government’s own financial regulators understood the practical impossibility and constitutional concerns associated with such an expansion.
Market Shockwaves
The regulatory debate unfolded against a backdrop of heightened market sensitivity. On the same day as the broader policy discussion, a mysterious Bitcoin whale moved 94,504 BTC — worth approximately $1.018 billion — in a single transaction, paying just $700 in network fees. The transfer, detected by the Whale Alert monitoring service and included in Bitcoin block #593468, appeared to originate from non-exchange wallets, adding to the intrigue.
The juxtaposition was striking: while Senate staffers debated whether miners should be regulated as financial institutions, a single individual demonstrated the very capability that concerned regulators — the ability to move over $1 billion across borders without bank approval, government authorization, or regulatory oversight. For proponents of stricter regulation, the whale transaction was exhibit A. For privacy advocates and crypto proponents, it was a powerful illustration of Bitcoin’s core value proposition.
Ethereum, the second-largest cryptocurrency by market cap, traded at approximately $170, while XRP sat at $0.25. The broader altcoin market showed modest declines, with most top-20 assets down 1-3% over 24 hours. Total market volume remained robust, with Bitcoin alone recording nearly $19.5 billion in 24-hour trading volume — a testament to the market’s growing liquidity and institutional interest.
Closing Thoughts
The September 2019 Senate hearing represented one of the earliest serious attempts to extend traditional financial surveillance frameworks to the foundational layer of proof-of-work blockchains. While Murray’s proposals did not advance into legislation, the debate foreshadowed tensions that would only intensify in the years ahead. The fundamental question — whether decentralized consensus mechanisms can or should be regulated like financial institutions — remains unresolved as of 2019, and the answer will shape the trajectory of cryptocurrency regulation worldwide.
The fact that both the US Treasury Department and FATF had consciously chosen not to regulate miners spoke volumes about the practical challenges involved. Yet the political pressure to “do something” about cryptocurrency’s use in illicit finance was building, and proposals like Murray’s provided a blueprint that future lawmakers might revive. For the crypto industry, the hearing served as a stark reminder that regulatory risk remained one of the most significant threats to the sector’s long-term viability.

Classifying miners as financial institutions would have killed Bitcoin mining in the US overnight. the compliance cost alone would bankrupt every small operation
Murray testifying that miners need BSA coverage while BTC was at $10,353. the government always targets crypto when prices are high enough to matter
Murray wanted to classify miners as financial institutions under the BSA. miners compute hashes and secure blocks, they dont custody funds or process transactions for customers. fundamentally misunderstood the tech
pow_defender_ the irony is traditional banks process trillions in suspicious transactions annually with full KYC. applying BSA to miners would have just pushed hashing power offshore to jurisdictions with zero oversight
funny how this proposal vanished once China cracked down on mining and the US realized they wanted the hashpower after all
classifying miners as financial institutions would have killed proof of work in the US. glad this never went anywhere
wouldnt have killed PoW globally, just pushed it out of the US. china was still 65% of hashrate in 2019, this would have accelerated that concentration
David Murray from Financial Integrity Network was doing pure tradfi lobbying. the BSA was never designed for protocol-level participants
Murray’s testimony reads like someone who skimmed a Bitcoin wiki page. classifying hash computation as financial custody shows zero understanding of proof of work
Murrays testimony reads like someone who read a wikipedia article about mining and decided to draft policy. the 10k BTC price reference dates this perfectly
regulators looking at hashrate and seeing financial institution is the most confused take of 2019
Murray wanting to classify miners as financial institutions under BSA would essentially make running a node require KYC infrastructure. totally impractical for a decentralized network
thats the absurd part. miners validate cryptographic signatures, they dont custody funds or know who sent what. BSA was built for banks not protocol participants
tx lawmaker fan is right – KYC requirements for miners would have destroyed decentralized networks entirely.
KYC infrastructure for mining pools is laughable. miners compute hashes, they dont custody user funds. Murray fundamentally misunderstood what a validator does
the irony of citing anonymity as a risk when BTC at 10k had more transparent transaction flows than most offshore banks. these hearings always miss the actual point
the transparency argument gets ignored every time. chainalysis and elliptic have been doing on-chain forensics since like 2015, meanwhile traditional banking still processes trillions in suspect transactions annually
Classifying miners as financial institutions under BSA is completely misguided – they validate transactions, not custody funds.
The BSA proposal from 2019 shows how regulators fundamentally misunderstand how proof-of-work networks operate.
misunderstand is generous, fincen knew exactly what it wanted. miners were the only identifiable choke point left after exchanges got licensed, so thats where the proposals went
David Murray testifying to expand BSA to cover miners in September 2019 when BTC was at 10353 was politically tone deaf. you dont regulate hash power like a bank, the incentives dont align
Tomasz N. the BSA was designed for financial institutions with identifiable counterparties. miners validate blocks, they dont custody funds or facilitate transfers. the comparison fundamentally misunderstands how PoW functions
oalamp_ good point about miners validating blocks vs handling counterparty risk. applying BSA to miners is like applying banking laws to the postal service for delivering bank statements
the postal service comparison is generous. miners dont even see whats in a block until after they hash it. holding them to BSA standards is like fining a printing press for libel
oalamp_ Murray argument about rapid and irrevocable settlement applies to the whole network not miners specifically. might as well classify every node operator as a financial institution by that logic
