Technical analysis is useful only in the case of inaccurate forecasting of the market path "range and stability" but the prediction of the rise or fall depends on factors such as:

 - Mempool: more unconfirmed transactions, the higher the probability of price rises.
 - News: divided into news affect the price directly, such as news of hacks and regulation and news affect the price in the future, as ETF accepted.

This is my personal experience and not reliable.
