Whenever the price rise then it should be considered as manipulation and whenever the price is down then it is the end...
This volatility is a nice characteristic of Bitcoin vs other cryptocurrencies or FIAT and it will remain
But, I do see in different way that the drop was manipulated and the rise was organic. I mean look at the price right now, people are happy with it, they like the $10k price, when it was around $7k or even at $8k people were uncomfortable, they didn't like it, they were thinking about getting out because it could go down even further before going up, basically 7-8 levels made them uncomfortable in general.
However, in the end when price reached around $9k (a bit bigger) they realized that is a fine level, they are not asking for $20k right now, they are not asking for even $15k, around $10k is enough for everyone, nothing more but nothing less. It is a comfortable price where we enjoy the price and start using it how it should have been, for spending and earning or basically sending and receiving.
