I am totally against this and any kind of implants, whatever their use is. Hopefully most of the society is also against it. That is way too far, and against human dignity, simply.
For we are against about it and even me I don't wanted that kind of human intervention of technology development nowadays, that's threat to human life as well as radiations will is present of we are implanted with that kind of bitcoin microchip. But to think about we cannot go against it if it will become mandatory for the government to use that for security reasons; mainly taking out everyones privacy at the moment of your life, although it has a sense of security purposes but still freedom will not be like what we have now without any strings attached that you've been controlled not according to your personal will.
