China, Bitcoin crash and DCC

I am somewhat new to trading (and super new to cryptocurrency) so please bear with me.

How closely will this stock mirror bitcoin?

I got in at 8.4 cents and am worried about China eventually banning bitcoin.  I have read that they are considering this because bitcoin makes hiding money from the government very easy.  The ban on Initial Coin offerings in China yesterday seems to be a first step in the process of banning cryptocurrency there.

If China bans bitcoin, this means that 20% of the world population would no longer be using it, surely this would be very bad for bitcoin. What effect, if any, would a falling bitcoin price have on the price of DCC?  How closely are they entwined?
