We all know, China is a huge country, Banning bitcoin exchanges in China will surely create a huge downfall of bitcoin value, China has a large volume of bitcoin investor, We presume the value of bitcoin followed by alt-coin will turns bloody in coin market cap. Big trouble to crypto investors.
Well any ban from any country would of course be a hard hit for btc whichever way ypu look at it. But the effects would eventually wear off in time and btc will recover. China has always been against this market but remember that bitcoin's all time high last year happened with an active chinese ban on exchanges.
Just like when china banned all the icos on their country, the prices of cryptocurrency in the market has decreased so much last year but still it does not matter because bitcoins managed to reach $19k dollar before the year ends so keep on holding your coins today in order to become wealthy in the future.
