Honestly speaking the bitcoin market is good as of now with slight improvement and not much dump except one particular dump before week or so which provided further pump, but are these manipulation just to for whales to cash out before the halving and then invest again at a cheaper value to get most profit of out it post halving? Are we going to witness major dump before halving?
Maybe this is possible because whales think it will make a big impact for the price of bitcoin to fall. This would create a fear for other bitcoin holders to sell their bitcoins as well. It is often the case that whales dominate the market and we should also follow them so that we are not stuck in the situations they create.
So no matter what happens we should always be prepared and let us keep pace with the waves that whales will make.
If there is a dump again, then I am sure it's because whale who wants the price of Bitcoin to fall then they buy when the price is cheap. But actually we can also make it as a moment to buy Bitcoin and sell after Halving Bitcoin later. The price correction will still occur before Halving Bitcoin and I think that is a natural thing.
