People's Bank of China(PBOC) is very obvious. Whenever the bitcoin's price surges to $1000. PBOC quickly do something to make bitcoin traders panic and sell their btc. So the bitcoin's price drops back again. But now it doesn't much affects the bitcoin's price this time. I guess their trick is not working anymore. Expect PBOC will intensify their actions against bitcoin.
No, I have a different view. PBOC does not look if bitcoin's price is more than $1000. Nowadays, has more and bigger problems but these are related to chinese upward trend to bitcoin but not only the price. That is, yuan was at very low last Tuesday and the the drop of Yuan was 6.6 percent against the price of dollar last year. This was the worst annual drop
since 1994. The chinese currency has fallen to its lowest level the previous seven years. This drop made the investors to look for a better currency in order to protect their funds. So we saw this raw intervention from the PBOC which decided to forbid customers of exchanges to withdraw their bitcoin and ltc but let them to sell their cryptos and to withdraw yuan hoping that will intercept their citizens to buy bitcoins and ltc.
