You’d need the mark of the beast to buy or sell anything.
Yea, the man antichrist will do it and that mark will condemn anyone and everyone who receives it as it will be an act of worshiping the beast and therefore breaking the first commandment of God,
Exodus 20
1 And God spake all these words, saying,
2 I am the LORD thy God, which have brought thee out of the land of Egypt, out of the house of bondage.
3Thou shalt have no other gods before me.
4Thou shalt not make unto thee any graven image, or any likeness of any thing that is in heaven above, or that is in the earth beneath, or that is in the water under the earth.
5Thou shalt not bow down thyself to them, nor serve them: for I the LORD thy God am a jealous God, visiting the iniquity of the fathers upon the children unto the third and fourth generation of them that hate me;
But if your real good at it, you can steal a lot....
