No, ofcourse not. If you are long term holder then you should not be worry with this condition. This is only part of cryptocurrency market volatility, if you have plan to hold bitcoin for 2 or 3 next year then you need to be more relax. If you want to convert tour btc into fiat in the near time then you should convert it now. I thought that the bear market will not forever, maybe next year the price of bitcoin will start to rise again, I guess the price can reach $100.000 when the bull market take it's turn.
In this kind of market, we have to be prepared, strategic, and should have a strong foundation of knowledge and commitment. In the game of volatility we should be wise and be brave enough to face its positive and negative surprises. HODL is one of the most applied strategies during the dip but it does not end there, it needs proper timing since market is always moving. We may have different approach and strategies when it comes to price correction, but what is important is that we know what we are dealing with, continue to learn and explore new things. Never be afraid to fail, don't worry much, be positive, take a look at the brighter side, learn from every experience and use them as a platform to grow and be strong.
