Your statement only makes sense if you want to suggest that through "market manipulation" we should do something to influence the market participants to sell less and create artificial "scarcity".
Well, that is not an easy thing to do in Bitcoin Market any more...
Currently, many parties are constantly doing this, including several countries and their rulers with their regulations, influencers with the hype they always build, and of course, fake news from several media outlets that encourage this because indirectly, this also creates the illusion of manipulation used to drain emotions, steps that must be taken, and strategies, including for some traders and those who always experience FOMO.
This has become an inseparable driving force because, although not everyone likes the decline in Bitcoin or when Bitcoin crashes, ultimately this is also a process that cannot be separated from Bitcoin itself. This is because when value wants to grow, fluctuations must always move to support a bright future, considering that with the existing system, we are aware that when there is a decline, an increase is definitely on the horizon, and we are just waiting for it.
