@greenroom, thank you for your comments and welcome to steemit

Does my steam power apply to the tube the same as steemit?

My response to your question would be that YouTube is an app that is built on the steem blockchain. So steemit and dtube basically have the same reward pool. Whatever it is that you post on youtube, it appears on steemit and you're able to earn rewards (steem / steem dollars). Please note: 25% of your pay out would be deducted and that goes to dtube.
Just do your best to develop your niche and join existing communities. It will pay off at the end of the day.

So if you bought steem tokens at $6 and now they are selling for $3, my response to that will be just to HOLD/HODL them as steem power. For now, don't bother about when the rocket ship is going to moonAs a newbie, I think you should focus on the value you are providing for the community. That is what will be rewarded. Cheers.
