Is there any different choice rewards (50% / 50%, power up 100%, refuse to pay)?
50% / 50% - This rewards half STEEM power, and half liquid STEEM / Steem dollars. The ratio of liquid STEEM to Steem Dollars rewards is based on the network conditions at the time of payment. This is the default spending option.
Power 100% - This option rewards 100% STEEM Power jobs.
Refuse to pay - use this option can not be rewarded. Voting will affect the position of the position on the hot list, but will not be rewarded from Steem's rewards pool. The reply to the post is still eligible for rewards.
Where does the new STEEM token come from?
Blockchains like Steem and Bitcoin generate new tokens each time a block is generated. Unlike bitcoin, all new coins are made by block producers (called miners), and the Steem blockchain allocates most of the new tokens to the rewards fund. Reward Fund to give users the platform to participate in the token.

How many tokens are generated by the blockchain?
Starting with the 16th hard fork of the network in December 2016, Steem started creating new tokens at an annual inflation rate of 9.5%. Every 25% drop in inflation and 0.5% drop each year. Inflation will continue to decline at this rate until the overall inflation rate reaches 0.95%. It will take about 20.5 years from the time the hard fork 16 came into effect.

How to allocate new tokens?
In the new token generated:

75% Enter the rewards pool between author and curator.
15% of new tokens are awarded to STEEM Power's owners.
The remaining 10% paid witnesses to power the blockchain.

What is reward pool?
A fixed number of STEEM tokens are allocated daily to the Network Reward Fund, often referred to as "Reward Pools." These are distributed to authors and curators for publication and voting.

How is the rewards pool between authors and curators separated?
Up to 25% of blog spending is rewarded to the curator (the person who made the position) as a reward for finding content. Another 75% is for the author. If curators vote within the first 30 minutes of creation, part of their curatorial rewards will be added to the author's payment. This part is linear with the age of the job between 0 and 30 minutes. Therefore, half the potential rewards will be given to the author within 15 minutes.

Reward pool will be based on who votes and how much to spend?
Every day a certain number of STEEM coins are added to the bonus pool. In the short term, depending on the number of votes, the number of coins paid may be higher or lower, but over time, anyone who votes will pay the full amount.

Voting at Steem is weight weighted. As a result, voters with fewer STEEM Power voters than SP have a greater impact on distribution, but their votes do not increase the number of rewards.
