Five hundred dollars is not going to happen ever now. Bitcoin will never decrease that much. Ethereum might because it is already lingering somewhere around 600 dollars but bitcoin is like 10,000 dollars at the present moment. I have firm believe that it will touch 30k dollars as predicted by expert within the duration of this year. It is just February. Still 10 more months to go and bitcoin rises ups in weeks. Once it starts surging, takes no time touching the sky.
