What if it breaks?

What are the
generally accepted long term channels at the moment?
It is generally accepted that you should
never sell your bitcoins for anything less than a price, which is
multiple times of the ATH of the prior boom.
- If Bitcoin is in its growth channel, and you panic sell in the bottom, it will cost you most of your bitcoins when you panic buy at 5-20x higher after realizing you were wrong. (If you panic buy threshold is lower, you end up always buying high and selling low, and diluting your holdings.)
- If it it destroyed, you have no way knowing it and being able to salvage the high point of your value. Salvaging a low point, is meaningless when the same outcome in fiat terms can be achieved by selling a few %-points more in the previous boom.
I gotta add that I'm long enough in the game and have my emotions now well under control when it comes to crashes. It's like being a Vulcan, I have those emotions, but I don't trade on them. I just wanted to ponder the implications of long/medium/2-3months up channels (we're now in since april) being broken. And your opinions about that.
Not selling. I want a Risto-Castle of my own
