The bitcoin price can be manipulated like other coins. The ZEC is well manipulated at the moment.
That is what i observed now with ZEC. There is too much promotion and new thread being created aside from hijacking other thread
For any any coin can be manipulated, I say Yes. If you have capital, you can control the price movement.
Zec and Augur both projects were hyip since the begining, people does play with both values, and we all know both of them will go under 1 bitcoin, it were already traded before some whales make it reach 3 bitcoins, thats new markets, and its the same as what happened into bitcoin in the begining, the bubble of 1000 dollars that people made bitcoin reach and fall out in seconds, bitcoin does have now a great community and big support, and make bitcoin go up nowadays are just milions to make it, and the market may not support, soo a waste, otherwise rich people that are into bitcoin would make those.
