It is new and that will change.

Hive-Engine is now open and some tokens are already moved over. That will start to alter the balance.

EXODE is going to be going live within the next month and that is going to provide some JSON transactions for Hive since that is being set up here and not on Steem.

The overall trend is fairly obvious. Most of the activity, due to the shift of the community, is on Hive.

I think Steem was dropped from Blocktivity.
