Manipulation exists in all sorts of speculative assets otherwise the market would not move. The point is that those who are trading for long have understood how this system works. If you basic knowledge and understanding of a project and its use cases is good you should be able to decide whether you can keep it for long term or short term.

Once you have the faith in that asset, like bitcoin you can get the drive to buy it when the market falls = avoid FUD and sell at the pump = profit the FOMO but not buy it.

Therefore practice to understand the market emotions and how you can use them. Remember that whales only start the manipulation but it is driven by smaller fries and then whales feed on that.
