Many got afraid for thinking that this is already the peak but they forgot to realize that what they said their intention here is to hold for long term. If they are afraid to buy now then this mean that they are not really prepared to hold bitcoin for long term since what they are seeing its current value and they afraid to see a dump since it will affect them so bad. Maybe those people are for trading so maybe for that they should follow their guts rather than gaining a lot of stress for thinking on everything they are not sure especially on their goals. And comeback later on their plan to hold once they learn on how to execute their plan to hold for long term.
Also people need to know that there's nothing wrong to take a profit at this current situation since its normal for investor to take something when they need it. What's important is there's still a balance left so they would not missed another good opportunity that they could able to earn once same good situation will happen and bitcoin price would pump again then reach for another new ATH.
This is only natural because Bitcoin's movement has been quite drastic in the last few months without any deep correction, so there is a fear of entering (buying) at this time.
There shouldn't be any fear of buying Bitcoin at anytime if the person understand the importance of investing on Bitcoin, I no that each investors is entitled to their investment decisions but using the current state of Bitcoin to determine if they will invest now or not is totally not advisable and also I wonder why most persons allow speculation to influence their mindset of investing on Bitcoin at this time because at first there was a rumor or rather speculation about the possibility of Bitcoin making some corrections after creating the new ATH which affected the mindset of most investors of waiting for the correction before buying and funny enough till now we have not really seen any serious correction on Bitcoin, so perhaps this is to show that people should keep accumulating Bitcoin and stop waiting for dip before buying.
It is their mindset you cannot stop an investor from thinking the way he wants to, because in investing you must look at the pros and cons before making your investment, so speculation is also part of the market because people can choice to believe the immediate information they are having at a certain time because you cannot just throw away rumours, so what you do as an investor is you try to pick vital information. as we speak at the moment some investors are on standby to look at the direction of the market after the halving to see if it will bearish or bullish for them to make their next move, and that is very normal.
