Absolutely. I think helping out new minnows is critical, but overlooked by those who just care about their own wallet and wish to be helped by others but not wish to help others.
Everyone is important here regardless of their wallet size. So you may be helping a multimillionaire and they may wish to return the favor. That should not be the motivation behind your reason to help, but even if it were, it still is helping others. One of my favorite things about steemit.
