Bitcoin price going down isn't always the effect of manipulation. The money that comes in to the bitcoin market should flow towards something else one way or another, and investors are free to do that. This doesn't mean manipulation at all, it's just taking profits. The market is already too big for manipulators to exist, or if they do they can only affect a portion of the market, but still not enough to induce bear markets of high severity and long durations.
The Bitcoin market is already too big for whales to manipulate, it requires very large capital to manipulate now. So I doubt that the cause of
the decline in the price of Bitcoin is due to manipulation by whales, especially with the many institutions that invest in Bitcoin in the long term,
making Bitcoin support prices stronger, so it's not easy to dump Bitcoin prices deep enough. That's why Bitcoin has so far been strong enough
to stay above $40k, and I believe Bitcoin price will recover soon. It is the most reasonable possibility why the price of Bitcoin dumps,
that's because quite a lot of investors are selling Bitcoin at peak prices. But there is no need to worry that the Bitcoin price will rise again soon,
because investors who were already taking profit slowly started buying Bitcoin again. Because right now the price of Bitcoin is quite low and
it seems difficult to expect Bitcoin to drop below $40k.
