Not Trump coin that caused anything. Trump coin is just one of the memecoins and behaved like one of the memecoins. Including the Melania memecoin belonging to his wife that is also a shit as anything shit. Memecoins have their time and the time has just gone as they are all falling.
It's not the coin but the people need to be blamed who blindly invested in that meme coin. If you are investing in meme coin then you need to keep the risk associated with it in your mind. It's just like gambling with your money and in gambling you either win or lose. For Trump coin, those who made an exit in first 24 to 48 hrs after it's launch have won the lottery while those who entered after that are struck with no way out.
