well by co exist do they mean china can use it for legitimate trades with merchants or do they mean they've bought enough now and want a quick pump before banning it again.
Why would the Chinese government manipulate the Bitcoin price?
They have better things to do than getting into something with a market cap of just 4.6 billion.
I don't believe they would bother to play with BTC market manipulation. But the truth is, if they gave a green light to cryptos and created friendly regulations, the market cap could easily increase ten-fold.
