First of all, it’s best to look around for a provider or service with the lowest exchange rate. Secondly, you might want to make the exchange before going on a trip to another country, so that you’re prepared. Modern neobanks offer multiple currency accounts within one wallet, so you can easily exchange money whenever you need to. For instance, with Genome, you have an in-built currency converter in both personal and business wallets. Most currency converters in city centers tend to have unfavorable rates. Finally, avoid withdrawing cash in ATMs in a foreign country. If you really need to do so, use a debit card instead of a credit one.
