Meh, the effect is probably small. As many has pointed out, even though there is still probably many BTC users in China, they've closed exchanges so it's no longer to move around the money. Sure there's HKers but I'm not sure how big of an impact that can make.
Better not hold your bitcoin during Chinese new year because you can lost much assets with bitcoin back to lower price, I think you can sell bitcoin right now and buy or investing when Chines new year day and get lower price, after few days later of Chinese new year bitcoin back to higher price and you can get much profit again, is easy how to manager with Chines new year.
Not sure about this. Even if it does fall on New Year the recovery after might not be enough for me to make a profit so I'm keeping them and just riding out the holiday. I'll just wait till May.
