If it falls to double digit it will probably drop upto 50-80$ but i think everyone will be buying tons of it so , that time will be small probably 1-5mins or such
Hearing the news that 66,233 BTC had been moved from a wallet that was inactive during 2014 made me worry, and if this was true and as much as that BTC was sold then there would be a big decline and could have an impact on ETH and would be below 100 $
