Supercomputer can Actually Track your Coin

[Ucy]

A Powerful computer can track every single Bitcoin you send or Receive and link it to you.

Yes, I think it is 100% possible and EASY to track all Bitcoin we use.

Just found this out while going through something. It's likely some countries have been using Supercomputers to track and link bitcoins to their Citizens.
The good news is, no one can touch nor seize the Bitcoin
