Indeed no youtuber is able to predict the future movement of bitcoin prices.
Even though they can guess but still they can't guess the price even though they are a big youtuber.
They can only make videos like examples of past years, but for the future they are the same as us.
What is clear is that a youtuber cannot make a video about how the market conditions will be in the future except only for market conditions that have occurred and can be watched by everyone. So there's nothing to rely on from a youtuber because if it's just a guess, I think everyone can guess it with a sound mind even though in the end it will be wrong.
