to predict the dump or pump movement of the cryptocurrency price in the market it will be very difficult to happen because cryptocurrency price movements are very difficult to predict and it is very difficult to learn that, but if you already have very much trading experience maybe you can understand a few ways when there is good news and when there is bad news at this time it will also be a reference for the movement of cryptocurrency prices.
Yeah prediction is very difficult and most of the predictions became opposite of the facts. I always take decisions about my coins according to the current situation of the market because I think that it is more reliable than predictions. For predictions you need complete knowledge and analysis of the crypto market. You must be capable to know the trend in the market.
