1. Be patient, don't panic.
2. Buy and hold.
The first attitude is very suitable to be applied and very many traders experience tremendous panic when they see the market price drop, especially Bitcoin is now at $18k.
It's becoming increasingly apparent that other coins are very influential on Bitcoin. So, the opportunity to buy to increase the volume of Bitcoin can be done again for long-term investments. The current market situation in my opinion is a very tough test to be applied by those who are impatient.
Do not panic. Everything will get better.
