It's becoming like the boy who cried wolf.
Eventually when China's bitcoin volume drops to zero, it won't work anymore and become a sad punchline to a joke.
You are right but when will it happen? Well I hope this happens sooner or later in the next 3 years so that we will see a more healthier growth and dump in price of bitcoin by that time. It would also take a lot of time before that happens because there are some persistent Chinese who doesnt really move their bitcoin a lot is still holding so it wont come that easily. Even if that is being said, btc price movements will be healthier every time a dump caused by fake news about China happens.
It has already happened. "China banned bitcoin" news have hit the newsletters of all media, including mainstream media. China can no longer make any damage to the price, they are already a punchline to a bad joke. Just keep on stacking BTC, now it's time to be extremely bullish. We literally survived a nuke, and we rose back to $4000+ levels. I am certain nothing can stops us now.
