What could be more important than the air we breathe? It is the primary element that holds all life, on Planet Earth; it makes organisms not just survive, but thrive.

You are absolutely right sir, nothing could be more valuable and more important because once this thing is no longer there, there won't be any race to run again in this life.

Will there ever be any substitution for the breath , no matter how hard will try nothing could be compare to natural oxygen lol,
The other substitute will always be expense and not lasting compare to natural breath

Good insight for linking it with cryto currency, I really find it valuable
