the bottom is $500 at best and we can never see the good old days of cheap bitcoin in $400 and that is a missed opportunity. and soon this $600 will also be added to the history of prices never seen again for bitcoin.
Most users have quoted the same that bitcoin price won't go down of $500. In my view if the steep decrease from the value near $800 continued we might gone down to $500. Now the price has been getting stabilized around $680. For this reason we won't touch $400 anymore.
Yeah $400 is not at all possible in coming days, even price will fall it will be around $500-550, nothing below then that and we can expect the price of $800 at halving.
If the price drops below the $500 range, it could just limit to small exchanges. The price will come back soon.
