No.

If you want better returns then pay attention to the bidding rounds. $3 is double what you put in.

In fact, lets break that down...

After you take out curation, you will receive 2.25, that will be split between sbd and steem.

You will get 1.125 sbd and 1.125 steem for a grand total of a 50% profit.

Even if you did not profit, these are bidding rounds, they go only as the bidding does. If to many people bid and it goes to high no one will profit. This is why most people pay attention to the rounds as I've suggested you do.

If you are ever missing a vote I will refund but not because you selfishly think you did not get enough profit.
