Peg: The problem with setting the peg value now is two fold. Firstly, no one really knows the economic result of pegging and it will create a lot of FUD. Secondly, we don’t know if the strategies being put forward with actually work. Unless someone like Charles Hoskinson is brought on as a consultant I don’t trust the process.
Two currencies vs one: Here I tend to think it is better to leave as is. If Steem/Steemit is growing and successful why mess with it. A potentially catastrophic change could eliminate the first mover advantage Steem/Steemit currently enjoys. The one advantage I see from a having a single currency is having all of the Steem value bundled. This would push STEEM up the list in terms of market cap for whatever that is worth.
