Honestly, 50% down in a week isn't bad if you rotate your portfolio to a chart.

Your watching coins now have a retest at fib 0.5, which is a good point to gain 300%—500%. Isn't that bullish?

If you're looking at UP ONLY, this market won't exist with only outflow. 

Be patient and decide whether to hold until it returns to ATH or sell and rotate to another position.

But if it is downing now 80%, it's the end.
