Buying dips is good, but I don't think the declining will happen as you expect it. Yes people will surely spend more on vacation and celebration than during their ordinary days, but will they spend BTC is a big question. Everyone is expecting a major bull run this year, and those vacations may look too pricey in the end. So, if you want spend some money on vacation these days, spend anything but Bitcoin. And, I think, Chinese people are aware of that too.
