What OP is telling is true that it always happens when ever the market moves up then all bad news will flow and everyone will start to fud of market to go down but it will go up. That is why who ever listens to this news and trade always make loss. Always do own research and trade
We need to always apply the strategy any successful traders usually use to make money during FUD news, especially when it succeed in having effect on the market, we need to always go opposite direction, when people are panicking to sell, we need to rush to buy because this is the purpose for which they create FUD news too.
FUD news are created to cause dump in price for pump to happen, so if we are smart to know the whales move, then we will always buy when price dumps through FUD, it wont be long before these same people create FOMO news that will create a urge for people to buy.
