It says that @steem delegated 15 HP into your account. So, go to the upvote calculator and type in 15; you will see that your upvote is worth $ 0.0001 .
Yep. It is worth a hundred of a penny. Each upvote consumes 2% of your voting power. Your voting power was at 98% when I wrote this.
It regenerates at 20% per day. That means you get ten upvotes a day. Your ten daily upvotes are worth $0.001 ... a tenth of a penny.
The reward pool comes from interest on STEEM. This is why the upvote value is so low. In general you need to have $250.00 in STEEM POWER for your upvote to be worth $0.01. Ten upvotes would be worth $0.10 ... your daily total.
365 upvotes would be worth $36.50 . So, $250 in STEEM POWER gives you a potential of $36.50 in upvotes. That is a good interest rate.
The risk is that the price of STEEM might fall. The price of STEEM is currently about $0.15. The people who bought STEEM for more than $0.15 are upside down in their investment.
Good luck and welcome to SteemIt.
