If some company or rich businessman tell they hate crypto they most likely just want to buy cheap. If they praise it they most likely want to sell. It is one of oldest business tactics.

Rich investors or companies act opposite way to average crypto guy. Average guys shill the shit out of coins they bought or buy and hate coins they sold. It is pointless from business perspective, but also have less impact. If I would I want to buy some coin, maybe 20 people would read that comment, when multibillion company do it then it is on the news, people follow those words and proce dump.

Haven't you seen all those bilionaires, companies and banks shitting on crypto few years ago. And now they own crypto. Well, guess what... The moment they told they will never buy it and called it a scam few years ago they already knew they will buy. That's common tactic. Happen all the time outside crypto. Few years ago one bilionaire investor told copper have no future, people sold, price dumped then he bought almost all copper on the market for pennies and shilled it so much price increased a lot. He know copper will increase in value, so he manipulated everyone into believing otherwise. And after he bought he both had a control over market and was able to make people FOMO.

Never be afraid of person that praise something before even buying, they have no idea how to buy things. But afraid of people that casually negotiate or thise that hate product. There is big chance they are just like some Gary Vee. If anything institutions hating on crypto is your clue to buy more and institutions praising it indicate it is time to sell.
