I second on that.Yuan is tumbling so is the world economy.But Bitcoin is still strong holding $400 level for some period now.30 day volume in the top chinese exchange is 5 billion yuan and almost 80% bitcoin transaction is in yuan so there's huge market to capture.
Dont believe on the reports of volume of trading in chinese exchanges they are all bogus with just creating a hype to promote their exchanges. chinese exchange are doing just internal trading and nothing else. and no one can compete with any altcoin with bitcoins. Because Bitcoins is the main source of conversion of all the altcoins and all altcoins value are compared with Bitcoins.
