This is an open discussion, so your thoughts more than welcome.
Here is what i think that happened:
"A few people with a lot of money, a few brilliant ideas and the will to fuck everyone up in order to make loads more money came up with a great idea: let's create digital money, some bullshit about fighting banks, some japanese guy that doesn't really exist, silkroad for a bit.
Let's give this Bitcoin thing value by pumping the hell out of it, and let it drop on a bunch of unwanted childs that dream of getting rich with this shit.
In the Meantime we will have an organized ring of scammers ( Karpelles, cryptorush, mintpal.. etc etc .. ) that will make us even richer.
We will also have another organized ring of scammers/devs that will create new coins so we can pump and dump the hell out of them to make even more and more money.
Once this shit gets regulated we will just leave with more billions and see ya"
Bitcoin pump and dump because that how it works and how people are adjusting on it's usage. The pumping and dumping value of the bitcoin depends on the rate of selling or the buying of it. Many people nowadays are also start to use bitcoin as their source of income so that the value of it become more higher. And don't panic when it is dumping because it will somehow pump again.
