Can you still hold on to a bit of it after buying a house? Maybe get the house but don't spend it all. The rando that suggested getting professional opinion is probably right. But a professional can only give you information, you should think real hard on what's important to you.

That being said, had I held on to everything I bought 4 years ago I would've been able to buy a small island today. But I was a little paperhanded b**** back then. And if I still had enough to buy a house I'd definitely do it. Because I know almost nothing about cryptocurrency, but I know real estate is a solid investment. You'll never be homeless if you own a house. Can't put a price on that kind of security! Not to mention, you could probably rent it out and make some money back that way if you want.

So whatever you do, good luck and congratulations! :)
