I give you one piece of advice: If you manage to solve the puzzle, do not trust intermediary websites for transferring your funds under any circumstances—this is the only way to keep your assets safe. The best option is to use the Electrum wallet, but make sure to download it from the official website. Then, send the funds like you normally do using the maximum allowed network fee. Don’t pay attention to the nonsense from users who are only trying to mislead others. Good luck!
