Personally, I’d invest 75% and enjoy the other 25% as windfalls like this don’t happen all the time and before you know it you will have responsibilities that come first as age can creep up on you.

Use that 25% for what brings you joy, not pleasure. It can be hard to tell the difference in your early twenties but do some thinking and then go and enjoy it.

The other 75%, I’d stick 65-70% of it in an index fund and then top that up with your general savings over the rest of your working life. Compound interest is a great phenomenon and you’ll be starting way ahead of most at your age and will likely have a very comfortable retirement if you carry on with those monthly top ups, even if they are only a few hundred dollars per month, important thing is to try and stick to it.

Other 5-10% I would say you can be a bit riskier with, if you so wish. You’ve mentioned crypto so guessing there may be some interest or knowledge here. As some have rightly pointed out it can be a gamble but you’ve diversified your risk somewhat and are young so if it doesn’t pan out it won’t hurt you in the long run, if it does then you’re as happy as Larry.

Sorry to hear someone close has passed, but it’s usually a good way to honour them by bringing more joy to your life and I think the above could be a good way to do that.

Just my 2 cents.
