If the price is low, Big Miners will either stop or switch(Not an option as of now). This is scary 
No it's not and this is fantastic because we have far too many miners anyway by a factor of over ten and the ones
that remain might not rip us off like has happened in the past.
Celebrate when most of them go not that many will since they are running the banker hubs on Lightning and
are hoping none of us noticed.
