While none of us can predict the future - I think it would be silly at this point to think of BTC as anything but a fairly high-risk investment right now. Assuming you can live off this for years and not work is a very dangerous assumption. I'm not knocking on bitcoin - I think it has great potential, and some interesting things are going to happen - it's a game changer - but you need to think more near term.

Given the current values (and remember, i'ts a market) - figure out the best way to dump it on a schedule - faster than you are now, and the tax implications.

Then, just figure out what that unexpected money means to you and your life - nobody else can tell you that.

Me, personally (and I'm not you, probably not your age, etc) I'd just stick it all in the bank and keep on trucking for a while, knowing I have an awesome cushion of cash in the bank.
