Don't sell your SP. SP will be worth 100 times more than SBD in 2-3 years.
You are right SP is the real thing. According to me as I see this platform it was not only meant to earn but to invest and earn. Steemit has helped a lot of people who were poor and now they earn through this. I think one should invest in steem and hold and should also earn through that. A lot of ways to earn are there on steemit, but I say invest money and start is the best option. I wish good luck to all who did.
And @nathanmars you are doing a great job, you actually care about the platform and you are focused on your mission, I admire you my friend.
RE: Q&A : Where would you invest your money, SBD or SP, given you'll stick around with STEEM for few more years ???
