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.
What's there to be scared about? This is just a good opportunity to buy more because there is a possibility that we won't see 18k per BTC again, the way the market is recovering this days it keeps pushing the bears to shame, just take few profits aside and if we go deeper you can use that to get more tokens.
