We should trust our experience in trading even though the situations got worst, and I don't think panic selling is the solution. What will happen to your future profit if you sell it all due to you're panicked? That's why we should stay stronger and keep the faith burning so we could stand against negative speculators.
Experience is also important but dont keep relying on it ,inorder to success in crypto trading you must educate and engage yourself espescially those different analysis and others, dont forget when you enter trade you should use your brain during corrections and in trading.
And this is something that does not even cost you a penny. Using brain is for free and the more you use it, the sharper you grow. Besides, using it in taking investment decisions in crypto is also a skill. Some people simply invest without evaluating the crypto in the market.
Also one should look back at the times of loss. Look what went wrong and how can you modify your plans and strategies to prevent further losses.
