I totally agree with you, the price never goes up in a straight line, but in steps.... There you show the steps (supports) that has been taking in the rise of its value.

Those who buy in the fall have to have a clear strategy, percentages, know the projection of the fall if it continues and be able to split our purchases so as not to exhaust the capital in case it continues to fall, among other things ...

Buying in the fall is wise. Well done!
