You're right he should have a reliable and trusted assistant to handle things, he should start trusting people, to handle money for them, it could be a relative or a close friend, Bitvest and 777Coin have huge transactions funds coming in and coming out there it should be monitored and handled properly, I hope in a month's time things will be back to normal and Bitvest and 777Coin operation will be normalized.
If he can't trust on anyone outside his family, why not he give some responsibility to his family or siblings to handle the financial matters in his absence.
Basically there are many users in this forum who are proven to be TRUSTED members who have handled huge amount of money without any issues. Lightlord can choose one of them to handle some of his funds so it can reduce the issue regarding empty hot wallet or any other payment related to his on going services in this forum.
