@rogerkver you are already invested in STEEM. From those potential $7,000 SBD that are currently showing on this post (due to the upvotes of several whales, namely @ned @smooth @berniesanders and @tombstone), 25% will go to the upvoters and 75% will go to you. That 75%, let's say potentially $5,250 Steem Dollars you won't cash it immediatly as SBD. You will cash 50% as SBD (potentially $2,625) and the other $2,625 will we paid to you in the form of Steem Power at market rate (currently $1,47 SBD/STEEM), that means about 1,785 Steem Power.
So you basically by virtue of this post are already an investor in Steemit with about $1,785 Steem Power that can only be divested over a 2 year period.
Now the question is if after learning more about Steem, you are going to divest ("power down") your STEEM or if you are going to use your SBD (Steem Dollars) to buy more STEEM ("power up").
PS: Also I wonder if I ever would reach $1,000 in Steem Power, but anyway will keep working hard to reach my goal :o)
Thanks! Your post has enlightened me a little more in my first week here.
