Are we in danger of falling below critical mass?
What needs to be done to allow us to BREATH again?
I do not know what do you mean in particular when you say "BREATH again", but I do know that we are working pretty fine in terms of adoption. Price per se isn't what a coin fully depends on in order to survive, though it plays a vital part in doing so. Adoption is what drives a coin to its success, and price is just a result of adoption (as to how I view it at least). With a great number of people using a coin, the potential of the coin increases, thus making it "alive" and ready for future growth.
