• Sell trade: if the trade executed successfully, the exchange move the frozen crypto assets from the user's wallet to LG's wallet at the exchange. The user will have a fiat balance. LP will send a wire to user's bank account, and withdraw the crypto assets from the exchange once every week.

If failed, unfreeze the crypto assets and return to the user.
