I am sure not all HODL'ers are thinking the same way. Selling off a percentage of the holding and selling off the entire holing are two different events. While booking a certain percebtage of profit is a normal occurrence, selling off entire holding is not. The analysis doesn't show any such possibility.
The truth is that market is bleeding and people are showing mixed reactions. But a true believer will never sell of their entire holding unless there is an emergency. We need our trust to bitcoin and focus more on spending it like a currency instead of just holding it if we want to see a better future for cryptos.
