Don't you see what Trump is doing? He is deliberately manipulating the market and driving down prices. Listen to his words and you will understand his plan.
1) Scare investors and ordinary people so that they start selling their coins and stocks en masse.
2) When the price drops, the government and Trump will buy everything with tax money and from his own wallet - and after that, Trump will be able to calmly manipulate the market.
When he says it's time to get rich - remember. They are getting rich, NOT YOU.
