STU=Steem Token Unit

That is really what is shown when you look at any post...it isnt in dollars they use the dollar sign.

Thus $1 equals 1 STU. If one opts for the 50/50 payment, it works like this.

1 = 50% SBD 50% SP (or 50 cents apiece).

Since 1 SBD = $1 (the face value) one gets .5 SBD

Yet SBD is $7.50 right now....meaning .5 SBD gets you $3.75 worth of STEEM.

Add the $3.75 worth of STEEM to the $.50 STEEM (from the 50/50 split) and you get $4.25.

So right now $1 STU is worth $4.25.

1KSP = 1000 Steem Power
