The world has lots of talents that will help in improving the world. Now as you can see lot of people are into crytocurrency that's means All transactions could be in crytocurrency because lot of people in the world are investing in cryptos and I'm sure that the world will introduce cyborgs In helping us to carry out a specific tasks very soon but we don't when.
