It is clearly not estimated based on current market value. If it was then, the current market value ( 4*1660) =6640 dollars. Something about this is not making sense. It's also not based on 7 day moving average because , in the last 4 days the price has been more than 2 dollars, so let's assume 9 /7 = >1.28. The 7 day moving average is definitely greater than 1. So by that calculation, this number should have been at least 1 x 1660 = 1660. So again, none of these explanations here are making any sense. So there is another true answer. Find out what the reason is behind this guys.
