An example, if you have 100K in US do you have to deposit more every three months? I transfer between accounts, use my cards from accounts, pay bills from accounts. Any of these will keep an account active. Which bank are you using? Some are worse than others in ALL regards..................I have to go into my bank and make a deposit Wednesday. I'll let you know. I don't think you can just endlessly shuffle money back and forth between accounts to keep them active.
