Countries without tax on crypto
...
Puerto Rico
...
Puerto Rico is not a country, it is a US territory. And while it has some interesting tax benefits, crypto profits are indeed taxable in Puerto Rico.
Ok, it's a state with some different laws. In Puerto Rico, if you qualify for Act 22 you don't pay tax for crypto. Unless they changed the law. link
