Answer 1

question 1) more specifically: if there are legal entities in Hong Kong, which countries should be considered for opening an account, or specific banks that are convenient to work with in Internet commerce and do not pay taxes?
on question 2): as far as I know, different banks charge different transaction fees for working with e-commerce systems. Therefore, I would like to understand which bank to choose.
