Don't you find it to be a bit shocking?
The manipulation news isn't shocking to most traders. It comes as a FUD and sometimes, it looks as if it is going to pull the market down but whatever happens with it, the market will still regain its strength.
FUD is just one way of manipulating the market. There are many more.
You can hack an exchange, pay off some politicians to ban cryptos, or pay off the police to raid crypto exchanges or search homes of traders. And let's not forget about the most common one: get fiat money to an exchange, publish fake research that seems to point at tether manipulation, wait for a dump, buy cheap coins.
