An interesting post - when I began reading it I said to myself - "how comes no one developed a TOR based cryptosystem?! Then I read about verge :)
It is really alluring - a coin that is completely private using a technology that has reputation and is battle hardened.

I do have wonders about the criminals using privacy coins. It's really great to have privacy for legitimate reasons but a solution should be found to try to eliminate or at least decrease the amount of criminal actions done with crypto, preferably it should be a decentralized method of some kind. We can't ignore this aspect as we all have collective part in the crypto system.

I would also like to point that TOR is not necessarily fully, totally secured, there were cases that should make us extra careful, read here if you want to dig deeper:

Overall - privacy coins are great! We just need to be aware of the moral problems and the risks that still do exist and stay careful even when we use a secret coin.

Thanks for an interesting article! I learned a lot!
