I've used all mine, I've voted a fair few T20s, if required I'll pull my vote from those lower down and pile in more T20s.
Having said that I've only got 29k SP (although that puts me well into the top 1000), it's probably mostly just a matter of the top 100 non-steemit accounts coordinating to get to 100M SP, maybe less?
Very important issue this, thanks for the post.
