From 1.4 to 15.8 BTC: How Do the Cheapest CBI Passports Stack Up Against Each Other?

Two of the passports on the 21 CBI slate are payable in Bitcoin, sit outside the OECD reporting net, and reach the same destination: a second citizenship you can pass to your children. They are also separated by an eleven-fold price gap. São Tomé and Príncipe asks $90,000. El Salvador asks $1,000,000. On June 7, 2026, with Bitcoin trading around $63,300, that is 1.4 BTC at one end and 15.8 BTC at the other. The instinct is to ask which one is the better deal. That is the wrong question. The right one is what each number actually buys, and which problem you are paying to solve.

The cheapest passport and the Bitcoin-flagship passport are not competitors. They solve different problems, and the price gap is the size of the difference.

Two Bitcoin-native Passports, Eleven Times Apart

Start with what the two programs share, because it is more than the price gap suggests. Both are citizenship by investment (CBI): a sovereign government grants citizenship in exchange for a defined contribution. Both sit outside the OECD Common Reporting Standard (CRS), the automatic exchange of financial account information, so neither jurisdiction reports your accounts back to your country of tax residence. Both accept Bitcoin as a settlement rail. Both close in a matter of weeks, not years. And both produce a real, hereditary passport, not a residence permit with conditions attached.

So the category is the same. The tier is not. At a Bitcoin price around $63,300 on June 7, 2026, São Tomé's $90,000 donation is roughly 1.4 BTC and El Salvador’s $1,000,000 contribution is roughly 15.8 BTC. One is the cheapest sovereign passport on earth. The other is the only one in the world denominated in Bitcoin. The eleven-fold gap between them is not waste. It is the price of two very different kinds of optionality.

What 1.4 BTC Buys In São Tomé

São Tomé and Príncipe runs the lowest entry point in the entire CBI market. A single applicant donates $90,000 to the country’s National Transformation Fund, and that is the floor: no sovereign-issued passport costs less. The number that matters most for anyone with a family is the next one. A family of up to four is a flat $95,000, only $5,000 more than a single applicant, with each additional dependent beyond four adding $5,000. Almost nowhere else does adding a spouse and two children cost the price of a laptop.

The process matches the price for friction. It is fully remote: no residency, no interview, no biometrics, and no visit to São Tomé before, during, or after. You assemble a document package, pass due diligence, make the donation, and receive the passport, typically with approval in roughly 6 to 8 weeks. The 21 CBI advisory fee is 5% of the government donation, or $4,500, which puts the all-in cost for a single applicant near 1.5 BTC.

What you get for it is more than a cheap travel document. São Tomé is Non-CRS, so your financial information is not automatically shared with foreign tax authorities. It charges zero capital gains tax for non-residents, so a non-resident citizen can sell a Bitcoin position or rebalance a portfolio without triggering a São Tomé liability, and zero tax on foreign-source income for non-residents. And it is a member of the Community of Portuguese-Speaking Countries (CPLP), which opens simplified residency pathways across the Lusophone world, most usefully in Portugal and Brazil. The passport itself carries visa-free or visa-on-arrival access to roughly 58 destinations, which is the honest weak point: this is a privacy-and-cost passport, not a mobility passport.

What 15.8 BTC Buys In El Salvador

El Salvador sits at the opposite end of the slate, and the difference is not only the size of the check. Its Freedom Passport, enabled by legislation passed in December 2023, asks for a $1,000,000 contribution settled exclusively in Bitcoin or USDT, with no fiat option by program rule. It is the first and only citizenship by investment program in the world denominated in Bitcoin. You are not converting your stack to dollars to buy a passport; you are moving Bitcoin to a sovereign that wanted Bitcoin in the first place.

The mechanics rhyme with São Tomé even as the figure does not. Processing runs roughly 6 to 8 weeks. The 5% advisory fee is $50,000, which puts the all-in near 16.6 BTC. El Salvador is also Non-CRS, and it taxes qualifying Bitcoin capital gains at 0%, though, as always, that is a Salvadoran fact and not a release from your own country of tax residence.

The reason the number is what it is comes down to what El Salvador is. This is the country that made Bitcoin legal tender in 2021. A January 2025 amendment, negotiated to satisfy an International Monetary Fund program, removed Bitcoin’s legal-tender status and made private-sector acceptance voluntary; what it did not touch was the 0% capital gains treatment, the citizenship program, the strategic Bitcoin reserve, or the gravity the country now exerts. It runs a territorial tax system that generally does not reach foreign-source income, and its government has kept accumulating Bitcoin into a sovereign reserve approaching 8,000 BTC. Tether moved its global headquarters there. The National Bitcoin Office runs the state’s Bitcoin projects. The passport reaches 131 destinations visa-free, including the Schengen Area. The 15.8 BTC does not buy a better version of São Tomé's passport. It buys a different asset entirely.

Where The Two Programs Rhyme

Strip both down to a checklist and the base case is nearly identical. Payable in Bitcoin: both. Outside the OECD automatic-exchange net: both. Closes in weeks, not years: both. Zero capital gains at the source on a Bitcoin position, with your home country’s rules still applying on top: both. A genuine, inheritable second citizenship rather than a conditional permit: both.

Both also ask the same thing of a Bitcoiner that trips up applicants everywhere: a clean, documented source of funds. On-chain settlement does not waive the compliance file; it changes what the file looks like. A long-hold stack with a verifiable acquisition trail clears either program, and that documentation work is largely the same whether you are sending 1.4 BTC or 15.8 BTC. The cheaper passport does not buy a lighter due-diligence review.

If your requirement is simply a private, fast, Bitcoin-settled second passport that you can pass to your children, you have already cleared the bar at $90,000. Everything above that number is buying something specific, and it is worth naming exactly what.

Where The Eleven-fold Gap Actually Goes

The roughly 14.4 BTC between the two contributions buys three things, and none of them is a marginally nicer passport.

The first is mobility. El Salvador’s 131 visa-free destinations against São Tomé's 58 is a gap of 73, and the most valuable entries in that gap are in Europe: the Schengen Area opens to the El Salvador passport and not to the São Tomé one. For a holder whose life runs through European business, banking, or travel, that single difference can justify the rest of the spread on its own. Visa-free Schengen access is not only about travel; it shapes where you can open accounts, sign a lease, or base a company without a visa run, and the São Tomé passport simply does not reach it.

The second is alignment. São Tomé accepts Bitcoin; El Salvador was built around it. The legal-tender history, the sovereign reserve, the National Bitcoin Office, and the largest stablecoin issuer in the world setting up on the ground are not line items on a brochure. For a Bitcoiner who wants their second citizenship to sit inside a state that shares the thesis rather than merely tolerates it, that alignment is the product.

The third is a different map. São Tomé's edge is not Europe; it is the Portuguese-speaking world. CPLP membership routes toward residency in Portugal and Brazil, a corridor El Salvador does not touch. So the two passports do not stack the same kind of optionality. One leans Lusophone and lean; the other leans European and Bitcoin-sovereign. The eleven-fold gap is the distance between those two maps, not the distance between a worse and a better version of one.

What Neither Number Buys

Before you weigh 1.4 against 15.8, be clear about what neither figure changes. A second citizenship is mobility and optionality. It is not, on its own, a tax exit. Both São Tomé and El Salvador are Non-CRS, so accounts held there are not automatically reported to your home country, but Non-CRS is not no-tax. Your country of tax residence still taxes you on its own terms. For most of the world that is a footnote, because residence drives tax and residence is something you can change. For Americans it is the entire story: the United States taxes its citizens on worldwide income no matter where they live or how many passports they hold, so neither a 1.4 BTC nor a 15.8 BTC passport moves a US citizen’s federal bill by a dollar. The passport is the prerequisite to a US exit, not the exit itself; ending the obligation is a separate decision with its own exit tax. Buy either passport for what it does, and never pay for a tax result it cannot deliver.

The price gap also behaves differently once a family is involved. São Tomé covers a family of up to four for a flat $95,000, barely above the single-applicant donation. El Salvador holds its $1,000,000 contribution flat across family size and adds only a small per-applicant processing fee, so a family of four still lands near 15.9 BTC. For a single applicant the gap is roughly eleven times; for a family of four it stretches past sixteen. Whatever your number, decide it with the whole household in the frame.

Which Number Is Yours

Run it against your own situation rather than against the other program.

Choose São Tomé if cost is the binding constraint, if you want the cheapest credible route to a hereditary passport, or if a family is involved: the flat $95,000 for a family of four is the most efficient family citizenship on the market, and the Portuguese-speaking-world residency pathways are a real, underrated corridor. At 1.4 BTC for the donation, it is the passport you buy when the goal is privacy, redundancy, and a low number.

Choose El Salvador if the budget is not the constraint and you want the flagship: maximum mobility including Schengen, settlement in your own Bitcoin without a fiat detour, and citizenship inside the one government that put Bitcoin on its balance sheet. At 15.8 BTC, it is the passport you buy when the goal is mobility and conviction, and the price is a feature rather than a bug, because it filters the holder pool.

And for the buyer thinking in terms of jurisdictional architecture rather than a single passport, the two are not mutually exclusive. São Tomé makes a fast, cheap, private base layer; El Salvador makes the mobility-and-conviction tier on top of it. Owning both is roughly 17 BTC of citizenship across two Non-CRS jurisdictions, one Lusophone and one Bitcoin-sovereign, which is a more resilient position than either alone. You can model both in sats against a live Bitcoin rate with our cost calculator before you commit to either.

The eleven-fold price gap, in the end, is not a verdict on value. It is a map of intent. 1.4 BTC and 15.8 BTC are not the cheap answer and the expensive answer to the same question; they are the right answers to two different ones. Low time preference does not mean no action. It means knowing which question you are actually asking before you move the coins.
