I believe that whomever wants to control the price of bitcoin will only do that within a short period of time and nothing more. So if whales are using their tools to keep their price down in order for them to buy more Bitcoin at a cheaper rate is because weak hands and traders will always sell in panic. Donald Trump tarrif increase only affected the market temporarily. He knows that he is bitting more than what he can chew and that was why he suspended the tariff increment for three months.
People are actually mistaken the news that affect market sentiment with manipulation, for you to manipulate the market you seriously need to have access to a large volume of liquidity to control the market, if I can remember the institution holding the biggest bitcoin is Microstrategy and they have relatively less than 560k and even them if they decide to dump the market today they can be able to actually do that within a short period of time.
What we see as manipulation is the market sentiment been manipulated, the market price depends on demand and supply so news like the tariff affected the market because the sentiment of investors were affected as such more supply was injected into the market due to fears of an economic crisis
