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.
Its always been part of reality to have these kind of possibilities and this doesnt only exist on crypto but this is already happening long time with traditional forex and stocks market and now as long there are elites or those people who are on the top of the chain then its not surprising manipulation would always possible to take place. For us retail traders or investors we cant do nothing but to bare with it since we dont have the capacity to fight of the trend or such decisions thats why we do mind up on utilizing that movement to make profits somehow.
