Frequently Asked Questions
Cryptocurrency Legal FAQ
Is my cryptocurrency considered a security by the SEC?
Whether a cryptocurrency is a security depends on the Howey Test. The SEC examines whether there's an investment of money in a common enterprise with an expectation of profits derived from the efforts of others. Bitcoin and Ethereum are generally not considered securities, but most ICO tokens and many altcoins may be. Each case requires individual analysis.
What should I do if the SEC sends me a Wells Notice about my crypto project?
A Wells Notice means the SEC staff intends to recommend enforcement action. You typically have 14 days (although this case be extended) to submit a Wells Submission arguing why charges should not be brought. This is a critical moment to retain experienced crypto enforcement counsel. Our team has successfully convinced the SEC to decline charges in multiple crypto matters.
Can stolen cryptocurrency be recovered?
Yes, in many cases. Using blockchain forensics and tracing tools, we can track stolen cryptocurrency across wallets and exchanges. We then use legal tools like civil RICO claims, fraud litigation, and working with law enforcement to freeze assets and compel recovery. Success depends on quick action—the faster you act, the better the recovery chances.
What's the difference between DOJ and SEC cryptocurrency enforcement?
The DOJ pursues criminal cases (fraud, money laundering, conspiracy) with potential prison time, while the SEC brings civil enforcement actions for securities violations with fines and disgorgement. Often, both agencies investigate the same conduct simultaneously, creating complex parallel proceedings. Anything you say in one proceeding can be used in the other.
Do I need a crypto-specific lawyer, or can any attorney handle my case?
Cryptocurrency cases involve unique technical, legal, and regulatory issues that general attorneys often don't understand. You need counsel who understands blockchain technology, the Howey Test, crypto-specific fraud schemes, digital asset tracing, and how both SEC and DOJ approach crypto enforcement. Our team combines former federal prosecutor and civil litigator experience with deep crypto expertise.
