I currently have what might be considered 'life changing money' to many.
WTF should I do!? What would you do in my position!???
Congratulations for your new wealth. If you have a lot of coins to spare, I would recommend selling some and switch into other assets. For example you could buy a house and rent it out.
If you don't want to work at the moment it might be worth to create a portfolio than creates some monthly cash flow. Holding bitcoins is a good idea for the future, but you would need to regularly sell some to have money at hand. If you would have a stock portfolio that pays dividends all year round you would be setup as well. Or if you want less risk, you could just buy some bonds.
