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. Fees settle via BitSettle. 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 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 over a decade 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 narrows deliberately to El Salvador and Vanuatu, with bespoke advisory for everything else. Bitcoin-first infrastructure, a 5% flat fee on productized programs, 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. Fees settle via BitSettle.
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 productize two: El Salvador and Vanuatu. Depth on two Bitcoin-native programs serves our clients better than breadth across a menu. Everything else is bespoke, scoped around the client rather than forced into a shelf. Curation is a discipline.
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 we can defend and decline the ones we cannot. 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.
