DX with money comes bad luck.
But I'd probably keep all in different banks. And ponder what I'd do with the money for my entire life.
I "think" this would be what I'd do after considering:
I'd save up half of it for my children in future and the other half I'd calculate how to use it in my life time.
If I might have to live for another 50 years,
500000 / 50 = 10000 per year.
Means about 800 per month for me to spend. I'd take up a permanent job still and use the money for my family and what I want like learning and having a vacation and I'd be living a worry free life
