I think the whole correction might not be over yet .. See how the market develops over the next days.. Buying the right coins now might be just as good, even if the market drops a bunch more, it will surely recover, be it a week or a month or 2.
If the situation in South Korea improves, then Bitcoin Cash can go up by quite a bit. During the past few weeks, it had lost more than 70% of its value. Another coin to look out for is Litecoin (if demand in China picks up).
