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 think it could happen because bitcoin can be accessed by anyone anytime and anywhere and no one can restrict people want to buy or even sell on a large scale because of all the confidence of the person in investing
