We wanna sell/buy products in Amazon, E-Bay etc?
We offer an address in Estonia. You can submit it as your Estonian address. We also provide invoices, if necessary, that set you up with this address. An even safer option would be to establish a company in Estonia.
In this case, no one can tell you that you are not tied to Estonia. However, the link with Estonia is what Amazon just need from you. Your citizenship is not important to them.
