It would be more of like a microchip implanted into your left or right hand that would contain both your public and private keys to send and receive Bitcoins.
So in case you want to send or receive some BTC, you would just pass your hand over at a scanner and it would perform the desired operation. This is would make it a very convenient and easy way to transact, and carry your Bitcoins with you anytime, anywhere. However, the only thing to be considered would be the security of your private key from within your implant, to protect your funds from theft.
Nevertheless, I want to know your opinion about this, since it would be pretty cool to have such a system to help spread mass adoption of the cryptocurrency.
You are right it is very risky when it comes to health and also in danger if someone will know that you do have a chip that you are holding a big amount of bitcoin thats it is risky. When it comes to healt it very risky also because we dont know if your body will accept the chip or not if your body will not accept it then it is very dangerous
