No, strictly speaking, if you are located in the United States, it’s against Deribit’s terms of service to use the platform. This is because of the USA’s tight regulatory rules for cryptocurrency exchanges and related services.
A look at user Deribit reviews reveals that some US residents are flouting the rules and still using Deribit. Users provide misleading personal details and utilize a proxy or VPN service to make it look like they’re accessing the site from another country.
You risk an account ban if using this method. It’s also much more difficult since the introduction of ID documents. Under the KYC system, Deribit even reserves the right to immediately liquidate your open positions if you access the site from the United States.
