manipulation just means buying and selling.... but you seem to be caught up in this delusion that volatility is somehow attributed to a implied immoral or even criminal "manipulation" as if the word manipulation is any more than JUST buying and selling and yes if you HAVE the money to buy or sell a cryptocurrency then yeah duh you can pump or dump the price but unless ur willing to keep it up your gonna end up having the price snap right back as you become just another bag holder or just another tetherUSDT holder...
