As BTH DDA Hard fork completed yesterday, the competition for hashing power between bitcoin and bitcoin cash will become even more contentious than ever before.
At the moment, BTC (segwit chain) lacks an emergency difficult adjustment protocol. When bitcoin cash rise in value, miners will leave BTC pool in drove, however the difficult adjustment in BTC (segwit chain) will remain unchanged in near two weeks. Such sudden drop in hashing power will lead to an absurd long time to form a block, and also the network congestion problem.
So in the week, we might see more drama unfold and some drastic change in price in BTC as well as in BTH.
