Antichrist is a person who will trick a certain group of people into thinking he is the messiah. He may have his portrait put on money, but he is definatly a person, not money.
Money is not the root of all evil actually; it's the means to overcome the limitations of barter so that you can reward contributions to society without having to do a like-for-like exchange which can get complicated. So the unit of exchange called money, exchanging an energy for contributions to society, is extremely positive. It's not an evil. Where the problem comes in is when you start having interest on money, because then purely by controlling the unit of exchange you can control the world and suck people's wealth into your hands -- which is what's happened.
