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.
If we already believe it will be different from people who still have a lot of calculations and of course everyone has different speculations.
Personally, I don't care about the continued increase because I believe that in the long term holding Bitcoin will be a big enough profit that I will continue to make purchases if I have the money without caring about high prices like now.
