I think most of the investors are dealing with this on their mind. Especially if you are a short-term investor, it really bothers people very much. Because you need to follow the changes in the price very regularly to make a better decision. But for the long-term investors, the situation is not that much I think. They start being like this especially when the price movements seem interesting.

It's sure and certain that people who hodl are actually the ones making the money and if you must hodl you will need to hold for a long term and try to look away a bit because always checking on the asset won't help it but always make u think nothing is happening or most time you might even get tired of holding or maybe  panic and sell when you see a dump on the market, hodlers doesn't check on the asset there hold so often and there are never a panic sellers, it only in futures trade that much concerned and time is needed because if risk management isn't applied a slight movement in the opposite direction might liquidate an account. So if you want to hodl bitcoin you must not be a panic sellers and holding for long term would really beneficial.

That's not exactly Bitcoin that is playing tricks on you, but they're just market makers that are playing with the price and they often do that in a way that is the least predictable for retailers to see the next move which means they could end up with more profit at the end.

That's why 90-95% of traders lose in long-term, and that's exactly why you should not try to be a trader if you studied it and tested it out for 1-2 years and it didn't work which means you're not one of the 5% or less that are somehow better in trading, investment is the better option for most people and all you need to do is find some good assets that you are optimistic about and buy them at a decent price(preferably dollar cost averaging it if it went down more) and be willing to hold it for a few years if you have to.

too much overthinking, I guess your zodiac is pisces 
actually, it's good too because you saw it from some perspectives.
I had that in my mind too, but it happened only when my portfolio does not balance (I mean proportional, based on my preferences).
my comfort zone is when I have enough amount of fiat so I can buy the dip and bounce back instantly.
In this situation, my mind will also think, that at least I already have that amount of money.

Yes, of course. That is a common behavior for investors who aren't in a confortable financial situation, so they try to act most perfectly as possible to maximize earnings and decrease loss chances. I just think we shouldn't play too much with our head, because we are in an unpredictable market, so all these thoughts are a waste of time and energy in end.

Try to set goals at the beginning of the investment, and don't change your plans once you achieve them.

At my first stages of being into Bitcoin learning and understanding how it is working, I have also been into that state wherein I find it really frustrating to decide whether I will take hold or better grab the opportunity to just claim my reward for the work that I have done with Bitcoin to secure that whenever it crashes, my profit is safe with me. But upon understanding Bitcoin and have already got through many ups and downs, I have manage to not to make things complicated on how things will be because I trust Bitcoin and such tricks playing into one's mind will be mostly upon the newbies or those who are just starting their journey with Bitcoin.

I think almost everyone will have that kind of stuff in their head if they are just simply putting money in bitcoin without making a simple analysis on how they think the market would move. Bitcoin doesn't play tricks in your mind, it is just you who is not much pretty sure of your investment. One thing you should follow when investing is to always know when to exit and enter, analyze the market just like trading, there's a lot of market tools that can help you, and by that you can avoid big losses.

Also, bitcoin at the same time is assumed to have price increase as time pass. So you don't need to worry much if you're planning a long term investment.

I agree, to think that bitcoin is playing tricks on our minds will require that bitcoin moves depending on our movements, but things do not work like that, the market does not care about us and whether we are invested in it or not, we are the ones that play tricks with our own minds as we are anxious about whether or not we took the right decision when we invested in bitcoin, and the only way to avoid this is to be completely convinced about the potential bitcoin has to change the way the world economy works, once you internalize this you do not get anxiety over being invested in bitcoin anymore.

I also feel that sometimes whether I take 10-20% profit from buying and selling Bitcoin is enough or I want to hold it, I always worry about it but I end up taking profits little by little rather than my assets being lost
