Yes. A person's health is the most important factor. And obviously, we all wish the lightlord a speedy recovery. There is no doubt about that.
The main question is, is it normal for a casino with a long-standing reputation like Bitvest to rely on just one person? Should we risk our money at such a casino? If the hot wallet is empty, why is there no notice on the site? At least that would discourage new deposits. People aren't comfortable with their money being stuck on some sites and reliant on the health of a single person.
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.
