Well... I would honestly miss them... without the witnesses, we won't have new blocks on the chain... and that means no place to showcase all these awesome googlies anymore...

hehe... I doubt they're gonna stop, though... no matter the price of STEEM, they still get STEEM for what they do and many do it for more than just the witness rewards... they eaither run a business on chain or they have some other "soft" goals.

I don't see any reason to be scared... always stay curious!
