That is great, IF... Well, none of us can accurately predicts the future.
Just a word of caution & gentle reminder to others, make SP investments only a small percentage of your total portfolio (maybe 5-10%).
SteemIT may have the first-mover advantage, yet who knows that other runner ups can easily over run it thru innovative, mass user-centered satisfactions.
Also, STEEM currency has high inflation which eventually lowers it value. We may get many SPs in pennies, resulting in just few bucks in total value.
Good luck to your investments!
