if you zoom out the chart, you will see another two lower support lines.
I forgot to put support line for another price
if 15 $ support break, we have a good support on 12 $
after that 7.5 and 3 are lower price support lines.
we need a huge sell volume to break 15 $. but it can happen.
always be ready for all two bearish and bullish movement by using capital management.
