For example it can give clear idea if Bitcoin stood its resistance when FTX collapse was happening or if China declared no bitcoin country etc etc. This is just example but such analysis can be done easily. On the other front it is easy to understand the pattern of specific coin, it’s volume, it’s growth and declining nature etc. This is the reason multiple time frames should be done.
I guess the FTX and China analysis is funny to me even though I understand the point you were making there but however, it is still difficult to see that through the chart except it is a fresh chart, probably the same day they happened. But if it is a long time ago, it may not be easy to know except you are specifically checking for that which may be of no use on the long run because that incident is not repeating itself again. But it is right to use different time frame for trade, it gives more direction for trend.
