You must register the investor's office, necessarily with the same mail as the bounty office. After that, the tokens will automatically become attached to the investor's LC. If you already have an investor's LC with the appropriate mail, you do not need to do anything, everything happens in an automatic mode. Create a stock account from the investor's LC. Then (after the exchange is launched) it will be possible to transfer the tokens to a stock exchange account and then dispose of them at their own discretion. The withdrawal to third-party wallets from the bounty cabinet is not planned.
