Well said. Lucky to have bought up STEEM at 0.0005!
You have left out an important factor though - don't vote too quick. If you vote at 0 seconds after the post is made, you are penalised 100% of your curation rewards. This penalty drops to 0% only after 30 minutes.
Of course, it's a balance between this penalty and being too late. It might make sense to vote after 10 minutes and take a 70% penalty if the post is going to go up to thousands of dollars by the time it hits 20 minutes.
Indeed. It is all about a balance.
