If you want to do it based on the technical aspects.
First understand BTC and ETH. Compared with other currencies, these two are the simplest and most technically based.
Underlying logic:
Technical analysis is simply mass psychology. When a price area is supported or blocked multiple times, this price area will naturally be considered as a support/resistance area.
Long players will close their positions when approaching the resistance area, and short players will also open positions in the resistance area. Then the basis for technical analysis is liquidity. The more people there are, the stronger the liquidity will be, and the more people will agree with the support/resistance effect of that area.
BTC and ETH belong to the market. Since it is the market, how can there not be many people?
