I have heard about how the values of coins do drop whenever there is an upcoming national holiday especially in countries where there are tons of crypto users and traders so I would not be surprised if another drop happens this February 16th. We know how  we have a big number of users who celebrate the Chinese New Year and so to pull out cash so that they can have something to celebrate with is prettu much understandable and so with the demand decreasing because of people pulling out, it's no wonder that others would take advantage of buying bitcoins when they are at a price much vulnerable and lower than how it has always been.  In my case, I would buy bitcoins if their value is something that I can really afford so that I have more of it too when the value kicks up again.  Hold on to it and let it grow for the time being.
