It seems like BTCUSD is just in an unstoppable beast mode of sorts. After the anxiety of the hard fork branching some of the blockchain BitCoin Cash (BCC), it would appear some of the investors who had gone to the sidelines in the fear of the fork causing a substantial drop in-price are getting back into the market.
The mainstream news coverage that the fork came with is also bringing alot of new buyers into the coin for their first times. In-fact my mom called me a few days ago, with part of the conversation being that she had just purchased her first coin "to see what it's about; I probed her no further.
Technically, there has been squeeze pressure [likely short covering] August 5th and 6th; that pressure pushed the price up with some decent strength, and since then the MACD positive divergence has only expanded..and the money flow continues to rise despite a tiny pull-back up here.
