Also, be wary of civil lawsuits out of the blue, attempts at extorsion, and blackmail. Like I mentioned earlier, lottery winners have a tendancy to blow through their winnings like it will always be there.
Quoting: AsinineWell since you don't have any dependents a living Will isn't all that important, but you should decide where that money will go in case of an accident.
and if people start throwing frivolous lawsuits at you, make sure you use your wealth to hire a great lawyer, counter-sue for at the very least pain and suffering, and make them pay for your defense. <:->
If you do decide to give money away, be sure to give to it BUSY DISCIPLINED PEOPLE (not freeloaders) who could use it for beneficial technologies (renewable/free-energy etc) or whatever your heart's desire is in making peace with yourself and the world.
All of this "advice" is simply me saying what I would do.
I couldn't deal with your burden.
congrats though, but also good luck.
