When you have just 0.00001 Bitcoin, You feel secure by just encrypting your wallet....
But when you have 36.000 Bitcoins, you will never feel secured...
Actually, you will not be able to sleep...
The best u could be doing, is to Buy a laptop without internet connection, running Linux. Save your wallet there.
Or hire a programmer to develop a System that will spread your Bitcoins in several addrresses being impossible to group it again by a person.
