So if my River account gets closed someday, you won't be able to tell me the reason why? BTW, I don't keep cash on River, only Bitcoin until I transfer it to my own wallet.
If it would get closed after being open for a while, it would likely be obvious to you why it was closed. You would think back of recent actions. The case flagged above is different and is about opening an account. As for keeping cash on the platform, any cash is always returned to the owner.
