Ok, but as we can see, a little move from their currency, Bitcoin rate also moves.. scary.
China holds the most amount of bitcoin, that is why every time that they DUMP their coins, the bitcoins price gets low, but this doesn't mean that they are the one who is controlling bitcoin, because the truth is no one is controlling bitcoin. We don't have to worry about its price fluctuation every time that China will DUMP their bitcoins, because it is just normal, there is nothing to worry about.
Even if they are doing this, Bitcoin will never die or something worst, some of us are thinking this way, but the truth is, bitcoin won't die just because this. Bitcoin solidity can't be ruined by those people who are trying to take bitcoin down.
