The only CBI advisory firm built by Bitcoiners, for Bitcoiners.
Most people don’t think about leaving until it’s too late. Capital controls freeze accounts. Passport renewals get denied. Exit windows narrow. A second citizenship isn’t a luxury. For anyone holding real wealth in Bitcoin, it’s infrastructure.
21 CBI is the only citizenship-by-investment advisory firm built by Bitcoiners, for Bitcoiners.
We understand on-chain proof of funds, Lightning payments, and self-custody. BTC, Lightning, and USDT are our payment rails. Credit cards and bank transfers also accepted as needed. Bitcoin is how we think, and Bitcoiners are who we serve.
Every CBI firm we approached treated Bitcoin as a red flag, not an asset class. They wanted wire transfers. We wanted Lightning payments. They wanted bank statements. We wanted on-chain proof. They spoke in fiat. We thought in sats.
The firms that eventually started “accepting crypto” bolted it on as an afterthought; a payment option buried behind fiat-first workflows and bank-intermediary conversions. We didn’t want to be tolerated. We wanted a CBI firm that was Bitcoin-native.
So we stopped looking and started building.

CEO, 21 CBI
Adam built 21 CBI after spending two years navigating the citizenship-by-investment process firsthand. Every firm in the industry treated Bitcoiners as compliance problems, not clients. He is a retired US Air Force veteran, holds an LL.M. in European and Comparative Law from the University of Malta, where his dissertation defended Malta’s sovereign discretion to grant citizenship through the Maltese Exceptional Investor Naturalisation (MEIN) framework, and spent 12 years at the US Department of Homeland Security on immigration policy. He has been stacking sats since 2020. Running sovereign infrastructure (Lightning nodes, self-custody, Nostr) since before it was fashionable. Now based in Buenos Aires, personally navigating Argentine citizenship, advising clients across four continents. Every engagement is encrypted, compartmentalized, and built around your timeline.
Adam begins accumulating Bitcoin and running sovereign infrastructure: Lightning nodes, self-custody, the full stack.
Two years of Bitcoin and CBI research during COVID. Adam found no firm that understood Bitcoin as an asset class. So he set out to build one.
The first Bitcoin-native CBI advisory launches as Bitcoin Lawyer, but offering every CBI program on the market proves unsustainable. The “everything to everyone” model fails.
21 CBI launches with a focused model: five curated programs, Bitcoin-first infrastructure, a 5% flat fee, and no hidden costs. Clients across four continents.
We don’t bolt Bitcoin on as an afterthought. On-chain proof of funds, Lightning invoices, self-custody verification; these aren’t add-ons. They’re how we built the firm. BTC, Lightning, and USDT are our payment rails. Credit cards and bank transfers also accepted as needed.
Our 5% advisory fee is calculated on the government program fee. That’s it. No markups on processing. No buried admin costs. No invoice that looks different at closing than it did on the first call. We publish the math that others hide.
Every engagement is handled in isolation. Encrypted document exchange, minimal data retention, no shared inbox, no ticketing system, no junior associate triaging your file. Your case is not anyone else’s reference material.
Most CBI firms list every program on the market. We carry five: the ones we have personally vetted, financially modeled, and would put a family member into. Curation is a discipline. Quality at the program shelf is how you avoid the bad files three months in.
Four continents. Residency applications filed firsthand. Banking systems navigated in person. Immigration bureaucracies dealt with directly in the jurisdictions we advise on. We know what the forms don’t tell you because we’ve filled them out ourselves.
We accept the cases we believe will succeed and decline the ones that won’t. Every applicant runs a preliminary due-diligence screen before the engagement letter is drafted. If your file has a flag we cannot fix, we tell you upfront and route you toward what we can do instead. That discipline is why approval runs at 100% among the files we accept: we decline the files we cannot defend.

“I’d talked to three CBI firms before 21 CBI. Two couldn’t answer basic Bitcoin source-of-funds questions. The third wanted me to wire fiat overseas without explaining the path. Adam walked me through every step on the first call, quoted the fee in sats, and stayed on the same encrypted thread until the passport landed.”

“The whole process took less than 90 days. No ticketing system, no junior associate triaging my file; just a clear timeline and compartmentalized handling end to end. The transparency on government fees vs. advisory fees was the part that sold me before I even agreed to engage.”

“I came to 21 CBI assuming I needed a Caribbean passport. Adam talked me out of it. Wrong fit for my tax situation, wrong fit for my travel pattern. He pointed me at a smaller program that actually matched what I needed. That kind of advice is worth more than any glossy brochure.”
