With there being a fee for every transaction, and I am just guessing that claiming rewards in the wallet is a transaction, just like powering up or down, that pretty much means no curation rewards for the small accounts. Pretty much no net reward for voting. The only accounts that seem to be benefiting from voting/curating are the larger accounts.
That being said, I am still here, still evaluating the cost effectiveness. Maybe I should join the dobartim crowd at least they are making 6.00 + on most of their post. (not gonna happen)
