Let the whales do the manipulation, we can't stop the manipulation of the whales, but as long as we don't panic and can be more patient, everything will be fine.
Panic and not patience are normal, not everyone can handle this well. At least, don't rush to decide anything, learn and analyze everything first before deciding something. Many people become victims of whales' manipulation because they rush to sell their coins or buy any coins. Also, the people who don't understand how whales work, probably those who never learned about crypto market trends. That's why learning and research (analysis) are very necessary for investors or traders.
Weak hands are mostly affected by this whale's manipulation because they easily panic and decide to sell their coins without even thinking its consequence. But if they only went to research first and create good analysis, they will not tend to loss in the end.
The fact that we know bitcoin is decentralized, then no one can control it except for those big whales who are holding significant amount of bitcoin so they tend to manipulate the market. Other than that, those negative news and events create negative effects in the market which will result into sudden decline of the crypto prices.
