After a while you really don't care anymore about the dips, on the contrary you see it as an opportunity to buy more. Of course when you are new you are constantly worried, you keep checking the prices even though maybe you invested like $50, then there are people with a ton of bitcoin who don't even check the price for days. You just need to get used to, that's it, it takes some time.
It has to do with emotions and when you’re still battling with that emotion, it’ll never make you feel good whenever the market is always on the bearish trend. Just like you said, constant worry will be in the mind of the newbies and only those that have accumulated more will even not be bothered about the price as the market dips. 10-20% dip could mean a lot to someone to panic while to some it may be nothing and will not even make them have a thought to feel bad. A prepared and trusted mind in bitcoin will always have the positive mindset that the price will always bounce back after a fall.
Every beginner will definitely find it difficult for them to be able to control their emotions when there is a decline but if they can be patient and continue to learn to understand well how Bitcoin works of course they will choose to take advantage of the decline and will be able to stay calm when there is a decline, but if they choose to sell assets when there is a decline then it will make them lose of course this is not the goal of someone when making an investment, so it is very important for every beginner to continue learning about the investment they are running so that they can make a profit from holding the assets they have.
