It's real, and I've experienced it too when I first entered the world of long-term investment... however, along with the experience I went through, I started to be stronger in holding, where when the price of Bitcoin started to fall from $71k to $59k I didn't panic and didn't sell BTC, because I knew that and I was still very sure that after the halving there would be a great bullrun.. and there was a bullrun for BTC up to $99k.. I sold my BTC above $80k gradually..
For those of you who still panic when you see the price drop, it's a good idea to check the fundamental analysis again and ensure your confidence in the future of the investment you have started... that's better.
