My biggest concern is the microchip and $ being digital. Money should not be numbers in a computer. If we are IDed w something like a low [credit] score bc of our social media which I'm sure we already all are (by Big Tech / the Shadow Gov) "they" may be able to cut off our access to $ all together. I'm strongly against the microchip & see it as the mark of the beast. I'm also against crypto currencies bc of these dilemmas. I have $ in XRP & others bc it's a wise financial investment atm. Bottom line is that CASH is KING. Gold & Silver. Even some kind of Barter system would be better.
XRP is basically a fiat type of system, in principle fully controlled by the owners of the algorithems (banks etc). BTC is in principle, not centrally controlled, as long as the nodes are all independedntly held. Covert finance is what can harm a lawful system. In an evil system, covert can be used to bring the system down.
