Even though we don't want to see the market crash, there will always be a correction irrespective of how much of it happens at any particular time. If you have been in the market for some time, it is possible that even all this correction happening, you are still very bullish because you have invested long before now so HODLing could be ok for that investor but at the same time, you could have sold sum and buy back to increase you assets and profits which I believe is better because dealing in crypto is an investment and in investment you want to make profit.
