NGH Group Certified in Chainalysis Reactor, the World’s Leading Crypto/Blockchain Investigation Platform

Following a rigorous vetting process and extensive education and training, the NGH Group is now one of the few private-sector firms certified in the use of Chainalysis Reactor, the world’s leading cryptocurrency and blockchain investigation tool. Until recently, this ground-breaking technology was only available to law enforcement, government agencies, financial regulators, and financial institutions that operated in the crypto space.

Full access to this comprehensive suite of tools allows the NGH Group to trace crypto funds and analyze transactions to pinpoint intersections between cryptocurrency and fiat currency—a critical step to finding and pursuing recovery of crypto assets. Reactor also permits the identification of crypto addresses and wallets that appear to be controlled by the same person or entity, assets that may not have been previously disclosed. 

“Identifying and tracing crypto assets differs fundamentally from any other form of financial investigation, and it requires very high-tech tools and methodologies,” notes NGH Group founder and CEO Nicholas G. Himonidis, a Certified Cryptocurrency Forensic Investigator and qualified expert witness in cryptocurrency forensics. “Through Chainalysis Reactor, the NGH Group can now provide law firms, forensic accountants and other financial professionals, and even law enforcement with more accurate, more comprehensive, and far more efficient cryptocurrency investigations than previously possible.

 “For anyone needing to identify or trace crypto assets and activity in a divorce proceeding, commercial transaction, hacking, theft, or scam case, this is a game changer.”

 With multiple certifications in the digital forensic field, as well as a background as a practicing attorney, Himonidis is considered one of the country’s leading experts in the field. Recognizing that expertise, the New York State Bar Association appointed Himonidis to its recently formed Task Force on Emerging Digital Finance and Currency.

How to Handle Cryptocurrency in Estate Planning

Image for Cryptocurrency in Estate Planning post

Unlike other assets, which can generally be identified and accessed with appropriate documentation, cryptocurrency differs fundamentally from a “custody and control” point of view.

Cryptocurrency cannot be transacted or “controlled” without the private key(s) associated with the wallet/address where it is stored. Assuming you even know the crypto exists, without these keys, all the certified legal documentation in the world confirming a client’s “rights” to a store of cryptocurrency won’t help the client gain access if the crypto is stored outside of a brokerage or exchange, in a non-custodial private wallet.

So how does a testator or creator of a trust make a provision to pass on those private keys and related information about cryptocurrency after their death while maintaining the security and control of those assets during their lifetime? Frequent news stories about stolen or hacked crypto assets attest to the difficulty of this challenge.

NGH Group CEO Nicholas G. Himonidis, a certified expert in cryptocurrency and an attorney himself, will answer these questions and many others during a continuing education class for the Estate Planning Council of Suffolk County, Inc. The program will present effective, practical strategies for assisting clients with this unique asset class as part of an estate or trust from a “custody and control” perspective without compromising the security of the asset itself during the client’s lifetime.

The session is scheduled for 5:30-7:30 p.m. on Wednesday, October 19, at the Bijou Restaurant in Melville, N.Y.

5 Steps for Uncovering Cryptocurrency Activity

Image for Uncovering Cryptocurrency Activity Article

The exponential growth of cryptocurrency has introduced new complexities when searching for hidden assets. Whether a client is going through a divorce, a business breakup, or another situation that requires financial due diligence or investigation, financial and legal professionals (and their clients) need to watch for any signs that the other party may have cryptocurrency.

Any suspicion of cryptocurrency demands careful exploration, which includes the following steps.

  1. For litigation, subpoena cryptocurrency brokerages and trading platforms in the United States. If the counterparty is dealing in cryptocurrency, chances are high that one of the top 20 brokerages or trading platforms is involved, and many of them will honor a valid subpoena for information.
  1. Search for physical evidence of cryptocurrency activity. When looking for evidence of cryptocurrency activity, conduct an old-fashioned search for tangible items associated with cryptocurrency, such as hardware wallets, Cryptosteel-type physical backups, paper address certificates, and recovery seed phrases.
  1. Mine available financial data for intersections between crypto and fiat currency. Forensic accountants should look for any payments to or from any known cryptocurrency brokerage platform or trading app. Other signs include large, unexplained cash withdrawals, which may have been converted to crypto on the black market or through Bitcoin ATMs (BATMs), or expenditure patterns that suggest a dollar-cost averaging strategy of crypto investment.
  1. Target cryptocurrency in discovery demands. Beyond asking whether the other party has engaged in cryptocurrency transactions, attorneys need to request specific information. For example, discovery demands should include specific identification of any cryptocurrency wallets, as well as the Extended Master Public Key(s) (xPubs), which allow read-only viewing of wallet transactions.
  1. Search the other party’s data and devices. After securing legal access, forensically examine the counterparty’s digital universe for detailed evidence of cryptocurrency wallets, blockchain addresses, active and deleted internet history related to cryptocurrency transactions, and any interaction with brokerages and platforms. (This is often the only effective way to discover peer-to-peer cryptocurrency activity.)

Following the above game plan will help uncover whether a counterparty has engaged in cryptocurrency activity and obtain critical information for valuation. For assistance with any or all of these steps, contact the NGH Group. Founder Nicholas Himonidis is a Certified Computer Forensic Specialist, Certified Fraud Examiner, and Certified Cryptocurrency Forensic Investigator who frequently lectures on crytpocurrency and blockchain investigations.
