In this article it’s important to note a couple of items. First this particular person has a large portion of the funds she manages in one place. That place is not something she can control at all and does not need that risk in her life. Second she has tried to diversify herself by putting funds into several places but places she doesn’t understand. Invest in what you know! At least With a portion of your funds. You do not have to manage all of your money but if your going to step out of the box do it in places you understand.
