When you are a newbie you can refer to something on tradingview.com
1.Technical:
RSI (Relative Strength Index) (14): RSI <30, oversold => should buy. RSI> 70 - overbought, you should not buy at this time.
Fibonacci: There are Support and Resist. When prices hit the S, P, R levels, the price will rebound, so You pay attention around S, P, R levels.
You should buy (support) and sell (resist) around these areas.
2.Chart:
The result is Bollinger Bands.
You can refer to the Bollinger Bands here:

I am also a newbie sharing knowledge so expect people to help. Thank you for reading

This is the very basic stuff that you can use in crypto, but you can only use RSI alone and you can profit a lot from it.
