Its a great idea really, but I dont think it will work for everyone. For me, bitcoin is enough, and once youre making a good outcome from it, if you plan another business, it would be more preferable to start on a physical business already. That way, if your digital investment fails you, at least you now have a physical investment that can give you a passive income.
As much as possible, invest in tangible assets also. Because digital assets may give you high gains but then, it may not be sustainable as you can't guarantee that you will always get the same profits.
Investment should be approach as long-term. If you can invest both digital and tangible ones, the more you spread out your investment, multiple profits will come back to you when these investments have finally paid off. However, sometimes this is easier to say than done. But one thing Im sure of, dont force yourself to invest on that thing if you think the right timing has not come yet. Wait and be patient.
