Why did Trump want to issue air coins?
The issuance of virtual currency by Trump is certainly not just for his family to make a fortune, but rather aims at something much greater, which is to explore whether it can replace the Federal Reserve and the US dollar in the future. At the very least, it could exert some pressure on the Federal Reserve that doesn't listen.
Furthermore, even if it cannot replace the US dollar in the future, becoming the second Bitcoin would be great. If Trump coins possess extraordinary virtual value, they could be used to form an army and pay military expenses. Having its own armed force could provide solid protection for the interests of himself and the Republican Party.
Of course, if the above goals cannot be achieved, then it would be perfectly fine to earn a lot of money for the family and the children.
