The most important part of investing in bitcoin is timing.

[Sendo12]

actually the most important thing is patience. it doesn't matter if you were late to sell, as long as you wait to wait someday prices will rise again. so start being patient now because bitcoin has started to rise again. and always remember to set the time and target to sell.

You have a point. But it is also great if we open positions at the right timing. We can better results that way.
