Yeah, I've been in crypto since 2016 and a lot of people have said a lot of things about BTC (both bearish AND bullish) but that doesn't mean there is a conspiracy to "tame" Bitcoin or systematically manipulate the markets or repress the price.
Here you're just referring to three random events
1/ The futures were well timed because the market was in a bubble and going straight up on very little volume, no manipulation, just market dynamic, plus the volume on futures were ridiculously low at the time, go back and look at the data
2/ Warren Buffet doesn't like Bitcoin, okay so what? he's said repetitively that he doesn't invest in what he doesn't understand
3/ Paypal might offer Bitcoin payment rails, they've changed their mind from 2017, again so what?
So where's the pattern here? What else you've got to prove that "they" control the market?
Market are dynamic and complicated beasts, embrace the uncertainty and the easy narratives, there is no "they".
