What you should know is that 1btc= 1btc.
If you bought some units of bitcoin, and after your entry point, the price of bitcoin dips. It does not mean that the amount of bitcoin in your wallet has reduced, it is only the price that dropped. So if you are at loss based on what you think, don't worry but use it opportunity to buy more Bitcoin with discount and hodli, because the price must recover, and even pump higher than the amount that you bought it. This is why you don't need to use the money made for important needs to invest in bitcoin, but your spare cash, because when you hodli bitcoin for long, you will make profit. However, if you panic that the price has dump as you sell your bitcoin, you will run at lost. Don't buy bitcoin due to FOMO, and bitcoin is not a get rich quick scheme.  This is because the price of bitcoin increases with time-line. I see every bear market as an opportunity for me to accumulate bitcoin. I am not a trader but a bitcoin hodler, if a need beginner bought bitcoin because he wants to go into trading, it is a wrong orientation because you must run at loss.
