I believe that knowledge is certainly more important due to various reasons. If you have knowledge, then you can grow a single dollar to thousands of dollars. If you have money, but if you don't have enough knowledge, then you will certainly end up blowing up your account.
For me I think both are equally important. You could have the capital, but without the knowledge you would end up wasting your capital. You could have the knowledge but without the capital the knowledge is useless.
