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.
whales will always be whales, they exist to do those thing and actually if this true it happens even before. no need to get fear about them as long as the market still exist there are a lot of individuals that could outperform whales in the market once it start to get healthy again, right now we are just simply on a slump.
