Blackrock are manipulating the markets constantly, which they can do easily because they own such a massive slice of cryptos that they can buy and sell large enough chunks of any coin they want to trade, and pretty much control the prices.
But every once in a while they want to really shake things up fast, and one of their tactics is to roll out Captain Chump for some WWF style theatrics. For the second time this year he did the "massive tariffs on China" call. It worked pretty well last time, but this time was even more spectacular.
And for their next shakeup they will probably use a variation of the "WW3" story again, because that is an old favourite that never seems to run out of steam.
As well as making all the usual gradual market gains from their manipulations, on Friday Trump/Blackrock raked in billions of dollars of rapid gains. This 12 minute video explains what has just taken place:
