It depends on your goals. The strongest passport for visa free travel is Mexico. The strongest passport if you're concerned about being jailed with no due process is the US. Bear in mind, the US taxes it's citizens on every dollar they make anywhere in the world, barring tax reciprocity agreements with specific countries, so there's no legal way around that, and a lot of countries will report your bank account to the US if you open one as an american citizen. With that said, if your goal is tax shelter stuff, there are plenty of passports in the Caribbean, Latin America and Mediterranean that can give you some benefit, that don't require too much. Some of them the investment cost is half a million, some of them it's a hundred thousand, for most of them it's an investment requirement, you're not purchasing citizenship, you get to keep the real estate or business you buy with the money. I believe the Dominican republic outright sells passports for 100k.
