Is it worth accepting only one method of payment or is it better to include several different payment methods? I'm currently developing my site and I have only one payment method enabled.

The more methods, the easier it is for customers to buy goods or services from you. I think this is obvious. There are customers who are uncomfortable paying by the method you choose.

You are right about something. Can you give me some advice then, please? About what is the best choice, how to act in this situation.

You should understand that currently accepting payment by one method on your site is irrelevant. There are a lot of users who would like to pay for the purchase with a card or through electronic wallets, etc. You need to consider providers that offer a wider choice of payment methods, for example, this payment provider https://solidgate.com/ allows you to choose among more than 150 payment methods and they can be implemented on your site.
