Powering up is the best option to do now with the spike in the price of SBD.
Because when you power up your upvote will be tangible enough, so when upvote yourself you can earn more SBD and Steem. Also when you curate people's work you earn more curation rewards.
A friend who powered up with the few Steem he had, his upvote which was worth $0.01 is now worth $0.03.
Here is the smart man! Nice :)
Thanks for that. It helps. But how do you know how much your upvote is worth. Most of the time when I upvote the amount doesn't change.
