If I enroll in a tear sheet program, it is my understanding I maintain control of the funds in my account at all times. I theoretically could pull them out, but if I do, then I would likely be kicked out of the program. Is this a correct understanding?

Yes, perfectly stated.  You would not only be terminated from the program, but you would also be blacklisted throughout the entire industry and most likely never again permitted to enter any platform anywhere.  They keep a shared database of such information.  They take this seriously.  A client who is given such high yields without moving or “investing” his money, and then who is so ungrateful as to break the contract by moving his money before the completion of the contract will never again be welcome in any BIIP.  Remember, these programs are “by invitation only”.
