Only converting is accepted for Dominican Republic. No order choice. There is no payment gate through PayPal or Credit cards or banks.
I know about localbitcoins but it's usually a bit more expensive than exchanges in terms of fees. Would really like to know if one of the major exchanges supports wire transfer to DR bank.
I guess there is no other option for you but
https://localbitcoins.com/country/DO. They are the best choice for you up to now. Does Dominican Republic support bitcoin? I live in a place where bitcoin is not really regulated but the laws do not force people not to buy or sell bitcoin. Therefore, we have many choices whenever we want to exchange our coins to FIAT. Many websites are built for this purpose without being tax although it makes the government hate bitcoin.
Just try localibtcoins. It is more expensive a little bit but its worth in your case.
