With the rapid rate of technological advancement, I'm eagerly anticipating the medical side of things. Nanotechnology showed a lot of promise and a few months back, there was an article of a nano particle being used to destroy cancer cells that are generally resistant to chemo. The possibilities that lie there...
On the other hand, with crypto becoming more and more recognized, those that seek to maintain power over the poor are looking into controlling crypto. I remember that when I was trying to get my account verified for a local exchange, I was initially disapproved because I put my source of money for the account as "cryptocurrency". I was told that the government bank would check my reason so I had to change it to something more "acceptable".
At this time yes, there is that control.
But decentralized exchanges will end up being online in the near future which means the governments of the world will have no say in who goes on there.
Hopefully, that is the case in my country. I'll be keeping my fingers crossed. We only have one local exchange and it's weird how cryptocurrency isn't considered a valid source of money for funding an account there. Because of the central bank having a say. And yet they accept bitcoin? Tsk tsk.
