And if you're getting started today in investing -- it's always a good time to invest. If you think that 10 years ago you should have invested in X, then in 10 years from now you'll be thinking you should have invested in Y.

For example -- buying BTC is a bit expensive today and will likely be more expensive in the future. You could buy 1 BTC today and hope that it goes up significantly in the future. OR you could look at Ethereum and realize that it's in a similar place to BTC and that in 7 years from now you may be wishing you had purchased it today.
