I don't fear fuds or regulators directly, what I fear immensely is that they may scared away miners. With current difficulty level it may be death spiral( huge difficulty against low hash rate ). To stop this core developers may be forced to hard fork. This may be the end of fireworks for long time..
But I see also light in the tunnel, but I am obliged to stay silent about that at least temporarily
That's not how mining works. If difficulty drops people with currently outdated equipment will get back into the game. The keyword is equilibrium. There is no such thing as too high or too low hashrate.
