No one knows when will this bear market will end. You will only determine that bulls are coming if theres a sudden massive increase in market cap of all coins.
As simple as that! Which is where monitoring of trends come in. This is not about predicting what the market is going to be like in coming days, what the peak would be or what the bottom will be. The fact is, no one knows and no sane person cares.
The only thing we have at our disposal which is useful is to make use of the price action, volume and trend in the market to make a decision if we should be getting in or not, based on what the whales might want. We are more like the followers, the whales are the leaders, and trust me; they lead by leaving footprints some times.
