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.
Nothing uncommon here, media spreading lies and misguiding information in order to give readers the wrong impression and opinion. There is no confirmation that this whale is going to dump bitcoins into the exchanges, perhaps he is going to trade them into ETH,BCH,XLM or some other altcoin. That will simply pump the market in the end.
