Many steemers don't know, why it is so important to convert SteemDollars to Steem and power it up to SteemPower. Here are my five reasons.
1. Converting SteemDollar or Steem to SteemPower brings you interest
Yes, that's true. Because Steem has an Inflation of 100% per year the SteemPower brings interest to not getting inflated and to keep it's inner worth. Here you can see, how much interest for your SteemPower you get: https://steemstats.com/ (enter your steemit username and choose SteemPower in the menu)
2. More SteemPower gets you more voting power to help reward awesome content
Steemit will be growing and staying successful, when the awesomeness of content is high. With your bigger voting power thanks to your bigger SteemPower you can reward content that is awesome in your view and down vote content that is not useful in your view. This way you can help to raise the awesomeness of Steemit.com. And that helps to raise the usage of Steem.
3. With SteemPower you become a stakeholder for Steemit.com
Your SteemPower is locked for two years. With this comittment you show to yourself and to the world that you are trusting the vision of Ned and Dan, that Steemit.com and Steem as a cryptocurrency is in the long run a good investment. This can convince others to join Steemit.com and will help to make Steem a cryptocurrency that will be bigger than Bitcoin some day.
4. As holder of Steempower you are stabilizing the Steem cryptocurrency
SteemPower is the backbone of Steem. Like your backbone stabilizes yourself. Imagine there would be a sub-class of Bitcoin that is "frozen" for two years. That would definitely stabilize the currency. Bitcoin has nothing like this. But Steem has it with SteemPower. That makes Steem the smarter cryptocurrency.
