who's going to complain more, old investors who has been hoping for the price to continue going up or the new ones that just saw it getting to $70k and all of a sudden it went back to $50k?
If you are asking between old and new investors, who's going to complain more about the fluctuation of Bitcoin then I'd say that new investors are more likely to complain more because old investors has been in the market longer and they know how it works. An old investor would feel disappointed and frustrated but only to an extent because they are sure that Bitcoin will always raise and they will never sell off their hodlings out of panic and fear of losses but a new investor knows absolutely nothing about how the market works and are more likely to experience the sense of loss or disappointment and potentially regretful about investing in Bitcoin as they were expecting Bitcoin to continue raising or at least be stable at the top and could be forced to sell their hodlings fearing further price drops.
This is exactly the case, it is expected to be so, new investors are novice in the system as such ordinarily as novice they are suppose to shiver once there is unexpected shift in the market that does not favor investors, as for the old investors they are known to have experienced one or two events that has taken place in the market so enduring whatever situation that comes as result of fluctuation wouldn't be a priblem for them, despite that it has been said several times that what newbies need is the basic knowledge, most of them has remain in that basic knowledge even after taking part in the investment for a while.
Bitcoin is a volatile asset which is its own character and I believe that Bitcoin being one of the most values currency is because of it is not a stable coin, every investor be it new or old should have come across Bitcoin being a volatile asset, I Believe that if newbies understand what volatility is, they wouldn't panic about price depreciation hence volatility works sideways.
