In Costa Rica cryptocurrencies are banned in banks. If you buy them using a costarican bank account, said account will be closed. At least, as far as I know that's so with the major state-owned banks, I don't know if that also applies with the private banks but that is the most likely.

I think the right term for the cryptocurrencies legal status in Costa Rica would be "not illegal", because they are not expressly banned, but they are not specially welcome.

They are not regulated and you can owned them without being taxed for them, and they can be even used in private transactions, but the government encourage their citizens not to use them, and I guess, there wouldn't be law protection if you are scammed using cryptocurrencies, but I'm not so sure about it. I would need to investigate more about it in that regard.
