This goes for any asset, manipulation via marketing and game theory is present in any market. People should always research the fundamentals and try to understand the thing they are investing in.
True, manipulation is happening in every market. And to those that have been leaning with crypto analysts and experts, I find it helpful and not sometimes. When I was new to the market, I used to believe those predictions made by the big names.
Some of them became popular because of the close call that they made. But most of them that predicted the market lately were too inaccurate to tell where the market is going. With regards to your funds, trust no one and play it on your own.
