Beside the point that I find thinking about "what to do with a lot of money" always an inspiring questions as it let you think about your goals in life - I find it specially interesting in the context of crypto.
Assuming you have put only on fraction of it into the crypto market and that fraction went up to the 50 million dollar junk. That means "blockchain" and "cryptocurrency's" are a success and you got a lot of gains. How much of the money would you really take out of that market? When is the right timing? Isn't that a sign that fiat money is in a crisis so why take out money at all?
Questions I have not yet found the right answer for but they are up in my head for quite a while.
