We should look at this problem from a different angle.

Without Chinese Gov's influence, BTC price should be higher than $1,000USD today.
How could BTC price went down to $400USD and that provided you an opportunity to buy more BTC?

Everyone knows Chinese Gov could not ban BTC in terms of technical aspect.
And eventually BTC price would continuously rise up in the long term.

So what Chinese Gov had done is to offer you a chance to buy more BTC and be more rich in the future:).
