Trump is completing his investment in Binance through the Abu Dhabi investment company MGX with USD1 that he discovered himself. Clearly, Trump's cryptocurrency landscape has quietly begun to expand the exchange segment, with an increasingly complete layout.
It seems that the earlier rumors about Trump investing in Binance, which CZ stood up to deny, were merely a farce. Eventually, Binance may lead to politics; in the face of money, politics can leave you with nothing, and both Binance and CZ are very aware of this.
