Truly unpopular opinion: Untraceable coins should have no future and are dangerous to democracy.

I know people here like privacy, but if cryptocurrencies go mainstream then if have to be traceable. So many countries have one (or more) of theses problems:

• Corruption in public procurement.
• Political party funding with injustificated money
• Secret lobby.
• Narco-states.
• Super rich who do not pay taxes.
• Bribery.

And the list go on. And as example, look what happen in Argentina:

Former Secretary of Public Works (at the time) José López was found with a bag with ~ $ 9 million that was hidden in a church.

With Monero (as example) these things would never be public and corruption would go unpunished.
