I don't think that it's normal for a Bitcoin investor to be emotional about his or her holdings, unless you are investing with an amount you can't do away with, but if you are investing with an amount you can afford to lose, bro nothing is making you emotional about your holdings
All investors are human, not robots or bots so human all have emotions and everyone is affected by human emotions. Difference is between people who can be more or less disciplined than others and have better or worse risk and capital management.
Those things are either well controlled or bad controlled that will decide those people reactions on a same market. You can have positive or negative emotion and feelings about the market but if you manage risk and capital well enough, and if you are disciplined enough, you will not either do FOMO purchase or panic sale. Because almost everything you do with your investment portfolio and decisions of purchases and sales are done very disciplined and less likely emotional affected.
That is why we must learn how to control our emotion so when we become an investor, we will not get the market affect. We can still calm down especially when the price fall but we can see a chance to buy back to add more amount. But if we don't learn anything, that will be a matter of time for us to lose our emotion control.
Having emotion control will also help you to prevent panicking when something goes wrong. You can adapt with the current situation without emotional because you are ready with that. With emotion control, you can run your investment without worry and still follow the plan.
It is very important for an investor to control emotions, if an investor cannot control emotions, he will not be able to sustain his investment for a long time, the market is never stable, and if you want to keep your investment in this volatile market uninterrupted, you cannot panic in any way, an investor makes wrong decisions because of his emotions.
The main thing is to never sell, just only buy, market declines are buying opportunities, but most investors make the fully opposite decision at this time, instead of buying when the market declines, they panic and decide to sell. And when the market rises again, they will just regret for the selling at that time.
So you can never panic in any way, People fail to make the right decisions because of their emotions, so if you want to invest in Bitcoin, you must keep yourself away from emotions, and always have the mindset to make the right decisions.
The thing that I did as investor is not too often monitor the market because that is the way to avoid me think negative and make me busy doing other things. This is the method that work for me so I can manage my emotion and not panic even when the price drop deeper like before. An investor must know how to manage his emotion because when he involve in something, he need to stay calm so he can think clear and react based on the current situation. Buy and hodl will be our purpose in Bitcoin investment so we must hodl on tight our Bitcoin and not selling it no matter if the market drops drastically. Just be patience and say to yourself that Bitcoin price will be back to the last high price and will jump to the very highest price.
