I think to get rich you need to invest in multiple products as only good investment can make you rich, if you prefer to save your money it will never make you rich, risks must be taken.
Why invest to many products I think that is very time consuming and you are not able to manage them all, better focus only to one if you can't.
But it is good if you can manage them all. And it could help you earning with bitcoins convert it to fiat and you fiat money invest it also to
other investments that would really help your investment.
