That is such a simple question it is hard to answer.
10B is more than any of us mere mortals can imagine so it stretches ones mind to think what would use it all up.
If it was just my money and especially since I am an old guy I would probably set up some kind of funds transfer to my children and grandchildren but not so much that it would use a lot of the 10B.
Next I think would be some kind of charitable fund (not quick enough to give a good idea of just what without more thought) like Bill Gates etc. probably aimed at some inexpensive problem solver for 'poor' countries. Something like the waterless toilet competition that is on right now and is aimed at putting hygenic, cheap toilet facilites out in the world that do not use water.
Probably some smaller charitable agencies that are trying to change the welfare of people not just extend the misery they live in.
Now if this 10B was only for income or capital expansion would need a different answer.
Being a conservative investor I would certainly spread it around a number of different endevours and fields.
Captial expansion would probably mean investing in land somewehre in the world but carefull consideration of where would be neccessay as I do not think North America has too many good investments at the moment.
Income stream from the 10B would seem to be a harder thing at the moment but maybe a small return from that much capital would still give you a lot of income so picking companies with a good record of dividend and again spreading it out would be my choice.
I never expect to get rich quick but I would hate to lose it all on one roll of the dice.
