They may not intentionally deprive themselves of the possibility of making a profit and they are trying to do by holding Bitcoin that they may psychologically assume that the current market situation is in their favor and the dips they expect in the future. The big financial companies have unscrupulous specialists who may try to manipulate it but this is to fill their pockets and to push the market price up to the point of increasing. They may not want to lose their capital by throwing it under the wheels of the bus. Therefore Bitcoin accumulators should constantly invest in Bitcoin and not sell their valuable assets (Bitcoin) to holders like BlackRock.
Like some time ago when the market crashed a little because of the actions of whales who sold a lot so that later they could get a cheaper price and blamed the newcomer, an AI-based application from China. This also caused market panic even though it was not much, but we who like to collect BTC even though the rate is small with DCA moments like that we must also take advantage of it quickly
I think that Bitcoin has gone past that level of being manipulated by a single person, before Bitcoin crashes by 5% just know that the selling pressure was too much on that day, market manipulation most happens in alt and shit coin, because it extremely difficult for an individual to pull down the value of Bitcoin base on the stash of Bitcoin he has. But market manipulation is none of my business because
since am not a trader, it is only traders that are mostly affected by market manipulations.Besides am also very confident that as long as you are a long term holder of Bitcoin, regardless of how the market moves or it's being manipulated, you actually wouldn't be bothered or lose sleep over it because those manipulation is just for a while, before it continues it magnificent surge upward, so the best thing to do as a Bitcoin investor is to buy aggressively when their is a serious dip in the market only if you have the financial leverage to do so, but on the case of the market being manipulated, that is the cup of tea for traders, not investors like us.
