I doubt you can earn the money back. You can certainly use that money to earn more money and keep it in the bank. If depositing it back into the phone was possible, crooks could prolong their lives while barely fulfilling the requirement of being "good for the country".

Plus, I think the point of dying after 10bil was used up was so they had to use it wisely. With such a large sum, if you can't realise your image with it, then you're probably not fit in the first place.
