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 If difficulty drops people with currently outdated equipment will get back into the game.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.
adjustment is done every 2016 blocks, what if we can't make this far
Don't worry. Megafarms have no choice but to keep mining as long as (data center cost) < (price of the coin mined). Even hobby miners have preordered gear that is yet to arrive at their door.
Mining ain't stopping any time soon.
I am not miner myself I have never been. I don't know what kind of mentality they have. Will they persevere in case price plumt suddenly to $50 bucks or will they drop instantly.
Without huge asic players network may experience serious problem lasting to new adjustment point. There may be need to support network for sake of its survival not profit at least in short run
