I have concerns about more than a few dollars in the bank as it is low hanging fruit for taxes and claw backs. Nothing will stimulate a business rebound like making the millions that people have stashed in banks or under the mattress get spent. Spend it or get it wealth taxed. Negative interest rates pop up in discussions from time to time.
IMO international bank accounts aren't for anyone who can't afford international lawyers and accountants.
Right now I can't get my bank to figure out how my cell phone payment went astray.
