I don't know about breathwork as a freedom tool, but it is definitely a balancing tool one can use to balance the parasympathetic and the sympathetic nervous systems, the relax/digest- and the fight-or-flight-mode. This way you may be able to prevent or to get out of burnout syndrome. So, yes, in that way breathwork may be considered a freedom tool. To me the "volatility" of Bitcoin can be seen as it's breath. It is breathing in and breathing out, sometimes with the also important pause between breaths.
In my experience, the impact of breathwork on my health & relationship with self has far exceeded balance and burnout. Not only does it allow us to shift from sympathetic to parasympathetic nervous system functioning, but it creates openings to altered states of consciousness, increased connection to our subconscious, and the creation of new & improved neural pathways. Love the comparison to the volatility of bitcoin. Specifically your mention of the pause between the inhale & exhale and the power that space holds.
Agreed, and I think it does what you describe because it can rebalance the autonomic nervous system. Strengthening the parasympathetical system implies enhancing regeneration. From my point of view connecting with the innermost self (higher self, heart, source, whatever you may call it) by means of meditation or simply healthy sleep is the ultimate form of regeneration.
