Here's some general advice: if you're going to make investment decisions off specific events such as what you've listed — chances are, you're going to end up having a really bad time.
As for trading, while you sure can make quick trades over pumps/dumps, not because a certain news is bullish, it doesn't mean you're going to make money through an upwards price movement. A lot of times, if a certain news is bullish but everyone ended up expecting that certain good news, your long positions can end up in a very very bad situation.
