More users using Segwit transactions will be what helps drain the mempool to get the fees down.  This will take some time as exchanges change their wallets to handle segwit (as mentioned in this post previously).  In the meantime BTC should get some more hashpower as some minors switch over to mining BTC from BCH.  BCH is around 2 mins per bock so as I am writing this I see this hashrate starting to change in the next 12 hours.  BCH will have a major difficulty adjustment upward this go around.  I do not see this cycle ending between BTC and BCH for at least a few more weeks.  Well worth the wait though.  Don't panic sell.
