I don't think we will actually see any currency at all. They will decide it is too expensive to make so much money, and would make tracking counterfieting almost impossible if it
was made a common currency. Then they will figure if they go cashless ( not the mark of the beast, just debit cards ) they will halt alot of sales of drugs and income fraud and will actually net them money. I see cashless as the next step it will probably be called ameros for the sake of naming it, but will likely be just CYBER DOLLARS. IMHO
John 13:34-35 A new commandment I give unto you, That ye love one another; as I have loved you, that ye also love one another. By this shall all men know that ye are my disciples, if ye have love one to another.Matthew 5:23-24 Therefore if thou bring thy gift to the altar, and there rememberest that thy brother hath ought against thee; Leave there thy gift before the altar, and go thy way; first be reconciled to thy brother, and then come and offer thy gift.
