The only secret that you should know is buy the dips (Bitcoin dips not altcoins), once you see a big dip in the market be rest assured that there will be a pump.
Signals can be wrong so your on analysis should be more prioritised than what others says, whatever be the outcome come it's your loss so you must be smart to know whether you have to take the risk or not.
Right. Just buy when the price is low, or when there is bigger buying opportunity. For sure that would create a big advantage on you when it's already a selling time.
Make your own signals and not rely on those market signals. They can't be trusted and reliable. If there's someone whom you can trust, that's only yourself most especially that crypto market is such unpredictable.
