At the end of May, Bitcoin hit a new high this year after a sustained surge, which began to reverse on May 25th and 26th. It once fell by 900 US dollars, a drop of more than 30%; China's bitcoin prices once fell to around 14,000 yuan, today About 14,700 yuan fluctuations.
Interestingly, the reporter noticed that the renminbis exchange rate movements from the onshore market are in stark contrast to the plunge in bitcoin prices. Also on May 25th, when Bitcoin turned down and fell, the exchange rate of RMB began to turn upwards.
The spot price of offshore RMB exchange rate CNH has risen from 6.8752 to 6.8498 from May 25th and has been rising all the way. Today, the intraday trading session of CNH rose to 6.8031. Onshore RMB spot exchange rate CNY, although closed today at the Dragon Boat Festival, rose to 6.8678 at 6.8860 on May 25 and rose further to 6.8525 on the 26th.
I suppose that there is no person on the forum who knows exactly why it is happening with Bitcoin so we just may make assumptions but no more. You are trying to bind Bitcoin with CNY and CNH I am not sure that it is right. I myself tried to bind Bitcoin with other assets like dollar (DXY), gold and the stock market (DJIA) but it was waste of time. I could not find any dependencies and ties. My stance is that currently Bitcoin is accumulating liquidity on the low values for the further growth but I absolutely do not know when Bitcoin will begin growing substantially again.
