I think there are different kinds of smarts, and ultimately it comes down to your goals. Someone who is a mathematical genius may not be 'smart' with their money, and could end up broke.
I think being strategic is better than smart because there are smart person who cannot do some things because they dont know how to do it, i mean what strategy he or she is going to do. Like in bitcoin if you are just smart and you do not know how to manage you money it will be nothing soon. But it is better to have both, if you are smart and at the same time you are strategic. If you have this both no wonder you will be successful and rich.
