Hive blockchain started one week ago. The community drive ana amazing blockchain tht broke off to form hive. Now the time of writing marketing action taken from hive are absolutely good. Steem token are trading half of hive token according to CoinGecko.
Steem=$0.168
Hive=$0.321
You would like to read that outstart is double as the mainframe blockchain.

Community Role:

See the true factor of community that how much can be a committed community tough and can't be bought. It's been outstanding 1st week of HIVE blockchain, where all major exchanges like bittrex, probit and ionomy listed the HIVE coin not only for trading, also for withdrawals and deposits. This is only just because of committed and passionate community.

Contentious split:

At the time of launch HIVE split, all contents and balance of steem accounts are copied and shows on hive.blog. So this is a network that isn't controlled by any non-Sun-controlled Steemit Inc. And there is no any ninja stake mined coin that hurt the community after sometime.

Conclusion, Not financial advice:

I think many of steem users are powering down and selling the steem as fast as possible. I am sure this will make selling pressure on steem blockchain, which puts steem under threat. People are using Blocktrades to convert their steem into hive.

I have also started powering down (not financial advice) of steem tokens after watching the recent condition of steem.
