BTC up by 6X in same time as STEEM is up by 9X.
Not sure I understand the market dynamics that could trigger a move in STEEM that is 50% more than the move in BTC.
Pure speculation by a giant whale I suppose could be one scenario that would lead to your result
Why could it not? Does it follow BTC solely? I just see the value in Steemit as it increases it's users and won't matter if BTC moves up with it, just my thought though, I am no expert by any means.
