I have explained that we know nothing about who created blockchain, but it allows every transaction to be traced. With a credit card, they can tell if you bought something. With Bitcoin, they can tell I gave you money first, and then you bought something. Central banks are moving to cryptocurrency because this will ensure 100% tax collection. The Bank of England was saying that parents will be able to control what their children spend money on. The problem is that the government will control what we too can spend on. Here is the BIS telling you the reality of the future. They want 100% of all transactions taxed. I suppose the girl next door will have to watch your kids for payment in kind — chocolate bars or clothes.
