I agree on the way how Asian celebrates their New Year, even Christmas.Bitcoin reached a new high on December last year, which We can assume that some Chinese or Asians, sold some of their Bitcoin to fiat to have a grand celebration. Nothing to worry about, Bitcoin will recover will reach a new high and i am confident to hold my BTC. Some people should try to understand and consider that this is a normal cycle on crypto world, Bitcoin's  volatility is normal and People should start embracing it and adjusting their perspective on this kind of events.
