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.
You can see that after recovering to the $ 8500 level, bitcoin prices have fallen sharply and there is no sign of recovery, is currently adjusted to the $ 7500 level. I think that this time you should only invest in altcoin to make a profit, because at this point bitcoin price altcoin price is constantly increasing, so I believe you can profit from altcoin .
