If you read news like this
https://www.ccn.com/mysterious-asian-whale-begins-funneling-funds-back-to-huobi/ that there is someone who has mysteriously bought a large amount of bitcoin. Then sell. All I can read is that Bitcoin has a fan of "Giant" who likes to invest and sell Bitcoin. This means Bitcoin will continue to run. What to worry about? What I do not want is if there is no Bitcoin buying and selling activity. Because that means Bitcoin no longer has any interest. That's what I should be afraid of.
This is just My Opinion Personally. Please fix it if it's wrong.
I also think like that so I think if there is a sale there will be a purchase but if bitcoin no longer has activity it will die but I think bitcoin will continue to survive and always be used for investment because this digital is very confusing and shocking for cryptocurrency who invest like a ball we will not know who wins and loses
