Investors profiting a lot and wanting to cash out. Reduced "consumer" confidence from the bcash shittalk.
Bcash cancer. Slander campaign. Not good.
Would be tough to blame Bitcoin Cash for all the problems plaguing Bitcoin today. In any case, Bitcoin's Cash is not increasing in price. Other altcoins such as Ripple and Ethereum are increasing in price now. The only people profiting from Bitcoin's price stalling are the altcoin holders. I do not expect this situation to stay this way for long.
I also don't think that this slump that we are seeing is caused by Bitcoin Cash, they have done their share of attacking bitcoin, but they are not successful. So for now, step aside Bitcoin Cash they have nothing to do with it. As for altcoins like XRP, I could only speculate that bitcoin investors are moving and shifting funds across to XRP, it has been pump at more than 50%, so it could be another contributing factor. Another is that is just the holidays, people cashing out spending their profits in this season, Its already Dec. 31 here at the other side of the planet, I have cash out myself so I attribute everything in the holidays. 2017 is almost over, and once everything has settled down, maybe we can see in the second week of January that trading will pick up once, and we may see bitcoin going up again. No need to worry and panic at this time.
