I joined steemit on 6th Jan '18. I had no previous stake on this blockchain before that and whatever I now have has been earned here on steemit. Since I have little in the token in my account, powering down holds no relevance to me. Maybe after a year or so I would look into it, but right now I feel powering up is the best option.

I have 100 SBD sitting in my wallet. I am waiting for a little better conversion ratio for SBD to steem and then I'll be converting it into SP. That my plan for at least 2018.
