I don't want to deal with things not being available in Discount Broker.
Plus with recent thinking, I have come down toonly proceed with brokers who have physical presence or a person I can contact in case of difficulties.
I don't mind paying high charges, but I absolutely need peace of mind.
It depends on country to country. Like for Europe, I can open a bank account so the client can just do a bank transfer and Wise will take care of the rest. But, say for Japan, the client should have a Wise account.
