If i won such a large amount of money, i would transfer everything but about 2.7M USD (15M DKK), into some kind of foundation, where i could give the money away to charities over the years.
2.7M USD is the amount of money an average Dane will earn over a lifetime, and seeing as im almost 25 and i have already made some money, that means i would be able to live slighty above average for the rest of my life. I'd like that.
