I see added value in exploring both Delaware and Estonia, especially if you're from a country in which online payment systems are very expensive to use, or difficult to acquire, for a small merchant, e.g. a startup.

Stripe and Braintree are really good options for merchants and may even have better fees than local options. For example, Braintree: 3.9% + 0.30 USD for accepting payments in your local currency using your estonian or american company.

Which of Delaware and Estonia fits better this use case?
