nobody knows for sure whats going to happen.. And why bitcoin cash ? if the matter is fees and scalability why not use the new raiblocks nano or even litecoin , dash ... ? There is a problem with the bitcoin forks. There are too many we are losing credibility. No more forks

If Bitcoin wants to be taken seriously, it may not be easy or legal to manipulate the market. While decentralization should replace the rules, there is obviously a way to do it before it is taken seriously. "As a major investment in cryptocurrency assets and as countries take steps to legalize bitcoin as a payment system (as Japan did in April 2017), it is important to understand how fragile cryptocurrency markets can be manipulated.

Despite all theories I seriously doubt that Bitcoin market can be manipulated. Not  for real.
In situation like this when the price is falling users are looking for reasons and market manipulation could be one of them.
But believe mr, there is no conspiracy theory and Bitcoin price is moving freely up and down.

I must admit that the market is rather predictable, this crisis we had all seen coming, so that it is also obvious is that the scenario was written

I really think that there are some manipulations in the market, i even think that the price fall is caused artificially to make cheap investments.

Why are you so sure about this? What are your arguments that crypto market cannot be manipulated, like any other market?

it will happen, but nobody knows In my opinion the market manipulation will only create unstable conditions, not directed and also lost value.

Bitcoin has experienced too much in difficult things, and it makes other altcoins also in the lowest position, and some even die, and market manipulation actually worsens the situation.

The amount of manipulation that is going on in most of these cryptos is ridiculous. They put the money into the market to give the common man hope and then suck the money right back out taking all of our hard earned money with it. It is the same old story, "the rich get richer, while poor get poorer." Wouldn't it be nice to have millions to be able to influence the price of currencies? The good thing is the big money is eventually coming! We don't know when or from where, but the fact that we know it is coming is the sole reason I'm not panicking from this huge dip. We are still a ways away from wide adoption so there is a lot of money to be made.

I believe that whales manipulate the price of bitcoins.No body can know what will be the in the next week. because the value is fall down straight. But we believe that the value of the bitcoin rise soon.

     You know what op, despite all the things that people say about market manipulation, I still do not believe that someone can really be able to manipulate the bitcoin market, I just don't see something like this being possible. Although it can really happen if a lot of wall street whales decides to team up and do it. But why would they? I mean, they are already in a good state in life living the dream. Why would they even waste time or risk some big values of their possessions just to manipulate a market like bitcoin? for fun? for money? maybe. But unless I get to see some concrete evidences that can prove this, I wouldn't bother worrying about it since I have more important this to worry about than this.

     Now, regarding the lightning network. I really do honestly think that this can be a very great thing for bitcoins since it can really solve the biggest problems that are really holding bitcoins back from reaching full success. Although I see it as something that is just a good fix  for the meantime while there is no true solutions yet for this problem, I still believe that this will be enough to actually draw in a huge amount of traffic back on bitcoins or maybe even more when it gets implemented.
