I think it depends on the bank that you are using, if the bank allows their customers to use their debit or credit card to purchase Bitcoin or other cryptocurrencies then it will be fine but also know if your country doesn't have a ban of using cryptocurrency. If coinbase is available in your location then you can try that or any local exchange. And just a tip, if you are not going to use it for trading purposes better not store your coins in exchanges, use a cold storage for it. If you can't use your bank to buy Bitcoin in your location then you can try using Bitcoin ATMs if you can find one near you.
