I can see you are a new member on steemit. Welcome.

Simplify this a bit for you. Currently steem prices are rising. Yet so is SBD. When writers post an article they earn by 75% of the money value of the post at the end of 7 days after they posted. The earnings by default is broken 50% steem power and 50% SBD. steem power is vested into steemit and you can't easily move, but you have higher upvote payouts. SBD is the crypto you can use to exchange immediately. The steemit system is suppose to have the SBD pegged to the dollar, so 1 SBD to 1 USD. Yet currently outside markets are pushing SBD up faster than Steem therefore any earning in SBD is a increase if converted to steem.

Also steem is a liquid asset so can be moved around immediately. Long term believers of steem would use them to power up which is put it into steem power. 1 steem = 1 steem power. This will never change no matter what price steem is. The key is to have a lot of steem power to earn more when you make an upvote.

Apologies for the long ass talk. Trying to help fellow members. I too do not know why the SBD and Steem are rising at their current rates. I am posting it to discuss and record present day occurrences. If you read my past few days posts I have been buying into this everyday, but as you can see today was better than yesterday and the day before and so forth. There seems to be no end to this.
