I thinks it's still because of rumors this Tron guy Justin Sun taking over steemit.
But as long as it's based on rumors it will not be sustainable, will it?
Well, we will see where we will end up. At least the volume went up from 300k/400k to 16.6 million at a peak.
As long as we have more volume (=in steem interested people), we should see some upwards trends too I think.
STEEM ON!!!
