What is your opinion about Tether USD? Exchanges that use Tether?

I've been reading about quantum computers, it can solve computation faster than any computing computer today, and it can also crack encryption it says, is it a threat for blockchain? and you can't hide anymore? it can be traced back to you so the decentralized thingy will later on be useless?  the cons is the U.S goverment will use it to trace and crack other codes and you can't transact anonimously? Can someone enlighten me please?

Bitcoin is here because people want to have freedom with their money, except the fees,lol, making it easier to transact with people in the digital world without the goverment or banks tracing it. It has its advantage when you use it in a good way,just a peer to peer transaction or buying investment online and buying coins,  the disadvantage is it is also  used in illegal way in the black market, giving freedom for those who don't deserve it.

The world is changing fast,and all those scifi movies coming into reality,  robots and AI are revolutionizing fast that you'll be amazed there is another invention out in the market, almost all project is for the convenience of people, making fast transaction, fast computations and accurate work, It is very exciting that people would have less work to do in the future,will it make people more lazy because robots will have to do the task?


From all those future innovation and revolution I hope people won't be too greedy and just use it in a good way.


What are your thoughts?  Plans for the future?
