A large number of binary options brokers accept various types of credit cards as payment methods for users to fund their trading accounts. Among the most commonly accepted credit cards are major international payment card operators like Visa and MasterCard, but some brokers also accept cards from other companies.
Credit cards in general is a fast and safe way to pay for goods and services online. However, they come with the drawback that the credit card companies have their own exchange rate, which may be significantly worse than the market rate. It is therefore best to fund trading accounts with the same currency as your credit card uses, whenever possible.
