The thing that makes me wonder about the usual advice about buying on a dip from temporary bad news is that it seems like an awful lot of people are planning to do that. If there is more money in people trying to buy on a dip then there is in speculators prone to panic-sell on bad news, then the dip never happens. Look at what happened on the blockchain split problem - it regained like 60% of the loss within a few hours, and all of it in 2 days. Just buying now might well be the thing to do. Or if you're going to try to buy on a dip, you probably ought to have your USD in an exchange now so you can react in minutes instead of days.
