For real, it can be kinda confusing deciding whether to use online currency converters or just hit up the local bank for dollar to naira exchanges. Personally, I've tried both.

When I checked online platforms like XE.com or even some crypto sites, sometimes you see a rate that looks kinda awesome. But the catch is, those rates usually don't account for the extra costs—like commission fees, transfer charges, or the "buy/sell" difference. And if you're not careful, some online services even have hidden fees!

In my experience, getting cash at a bank is usually safer, but banks almost always give you a slightly worse rate than what you see online. For example, I saw on a Korean site that for the dollar vs won, there are all these different rates for buying, selling, and sending. It’s basically the same with naira—your buying rate is usually different from your selling rate.

Overall, if you want the best deal, you should compare total costs (not just the rate) and check what’s actually available at the very time you’re exchanging. And don’t forget, with both options, rates can change a few times every day! So, either way, be careful and make sure you know exactly how much you'll get after all the fees.
