Do you mean currently or permanently?
Currently, on the contrary, I see that the rise in most coins is an upward trend, not a downward trend. You do not have to look at the narrow time frame, but you have to look at the chart as a whole, or over a certain period of time, for example, a month. Then you will see that most coins had an upward trend.
We are now in a bullish season, so I think that most of the charts are more bullish than bearish, but perhaps what you say is correct regarding the short time frame of 15 minutes.
