Generally speaking, diversification is very very important.
Even though bonds, stocks, or other items might be doing poorly at the moment, diversification protects against a precipitous loss. So get some of each sort of security, some real estate, some counter cyclical stock (aka invest in companies that do fine in down markets). Make sure you get very comfy with your insurance agents as well: Liability and Errors and Omission insurance are very important now, as you're a target. Make sure you're properly covered on all your properties and that you use limited liability mechanisms with all your business ventures. Be very careful you understand what actions as a board member/fiduciary officer are not covered by the policies.
Additionally, keep more than you'd think is useful in a cash/near cash account. Opportunities arise quickly. The ability to write a 200k check this afternoon can make you many times your 5m sometimes.
A very serious aside:
At the same time, be very careful of deals with ??? in the plan, especially with people related to illegal drugs. If you're not sure what your money is going, it might be going to normal wasteful stuff, or it could end up related to drugs.
This is a good way to find everything of yours frozen, and you finding things getting seized (I looked at some of your old comments is why I mention this point, having known people who have had run ins when in a position like yours).
