I have a serious question after reading this thread:
https://www.reddit.com/r/Monero/comments/6em8ep/how_to_get_monero_to_really_take_off/
If you use Bitcoin or Ether to pay your goods (or sell some) it's a hassle to break the chain between fiat (your identity) and your trading partner. You have to use tumblers and buy with cash to hide. And everything is recorded in the blockchain. Forever.
With monero you just shouldn't publish your darknet-address in the clearnet. That's it. Everything else is easy. You just use a wallet on your PC (some TOR would be good) to withdraw from any exchange (where you can buy XMR with your real identity). Then you pay for your goods. Easy. When you send money, the receiver even don't know your adress.
As a seller just transfer your XMR to an exchange and get your dollars. Nobody knows where your Moneros come from. They are completely fungible.
The blockchain is completely opaque. No values, no addresses recorded unencrypted. All transactions are unlinkable.
The only downside: no multisig yet (but planned)
Why nobody is using it?
I would be happy to discuss here and try to understand.
Monero (gui wallet) wasn't working on Tails until 2.12 due to some library dependency issues.
Still have to transfer in/out to btc, no way to just 'buy' monero.
I believe they are working on or talking about subaddresses, so you could publish one clearnet address and one darknet address and they still wouldn't be 'linkable'.

Theres 2 off the top of my head, but personally, I love it and the ideas behind it.
