I have an argument against:
You are much better off taking it out and investing to other currencies.
Your SP doesnt mean so much, your connections and networking does. I have made much more money thanks to interaction with people (or...whales) than upvoting myself.
And those whales didnt upvote me because of my SP, but beacause of the value I provide.
My not gonna take my SP out any time soon (maybe if Steem hits 2 digits).
Im not gonna invest into it eighter.
