Based on the current market situation , I would suggest you to study this article on market structure.

Crypto is a trending market when it catches a trend it usually keeps going into that direction and this is why it is so important to know how you can identify if the trend is bullish or bearish or it's about to shift into the opposite direction.
Identifying The Bullish trend
To identify a trend it's always better to start from the high timeframes because it doesn't matter what's going on in the lower timeframe it will end up going into high timeframe direction. That means you can use the lower timeframe price action to execute on your high timeframe setup.
The best timeframe is 1Day and weekly chart.
Now let's have a look at how bullish trend looks like

When the trend is bullish you will see price is continuously creating higher highs and the higher lows. This is an indication that the trend is bullish.
Here is the live example of the trend.

Look at the chart above. Price didn't break any of the low and this is your confirmation that the uptrend is still intact and you can continue to be bullish on it.
Where can you enter your trade?
Nothing goes up in a straight line. Lower time frames will provide you pullbacks while high time frame just consolidate. for example look at the chart below

It looks like the high timeframe is just consolidating but it's actually a 32% price drop which you can catch using the lower timeframe charts.
When price drops into high timeframe key zone (Previous higher low) that area can provide you an entry trigger and the target will be new highs.
Identifying the bearish trend
As the same as bullish trend but in an opposite way

When the price is creating lower highs and the lower lows this shows the trend is bearish.
Here is the live example.

Where can you enter your trade?
If you're interested to short the market when the market is bearish. The method is the same as trading in the bull market. When lower timeframe gives you a bounce into the high timeframe lower high zone. You can look for a short trigger there and the target will be new lows.
Identifying the Trend Shift
No trend lasts forever and this is where people lose most amount of their money.
If people are bearish and the trend shifts to bullish they do not accept it and keep shorting the market.
And if people are bullish and the trend shifts they don't accept it and keep buying the dips.
How can you identify a trend shift?
it's quite simple you can use the same trend strategy you were using to identify bullish and bearish trend.
When bullish trend breaks

when the market breaks a bullish trend you will see it will break below the higher low. Once price does that you can shift your bias from being bullish and wait unless if you get another bullish confirmation.
Some people like to take profits on their buys as trend breaks or some people like to open shorts depending on the type of traders they are and depending on how they want to trade.
Here is the live example when price broke under the higher low

When Bearish Trend Breaks

Similarly when the price breaks above the lower highs it indicates that the trend is now shifting from bearish to bullish.
Here is the live chart example

This is exactly how you can identify different market trends.
Just be bullish when the trend is bullish and be bearish when the trend is bearish.
Shift your bias when the trend shifts.
This is the only way to survive and be a profitable trader.
