Cryptocurrency is the next step in transferring money. The covid vaccine, upon injection, will have nanotechnology that, along with all other personal information, allows the subject to conduct monetary transactions via cryptocurrency such as bitcoin. These ways of transactions are done via the internet in a digital environment. There are no more physical transfers of monetary transaction as in transfer of cash, coins or cards.
Since the vaccine and its partner, the immunity passport, will go hand in hand, it will be impossible to possess either without taking the vaccine. Herd immunity may only be achieved through people globally getting the vaccine, and therefore globally buying and selling. It is optional at first, but it becomes mandatory. This vaccine/passport "mark" will enable authorities to recognize who received the vaccine and who didn't. Therefore, those who do not vaccinate are denied ability to buy or sell, because they don't have the immunity passport of cryptocurrency.
This is all a premonition of what is to come. It is not conspiracy theory, it is Bible prophecy playing itself out and culminating in the Rapture of the church and arrival of the Time of Jacob's Trouble.
