Have you heard about Bisq?

Bisq is an open-source desktop application based on blockchain technology which allows you to buy and sell bitcoins in exchange for national currencies, or alternative crypto currencies.

Its fulfilling Satoshi Nakamoto vision:

What is needed is an electronic payment system based on cryptographic proof instead of trust.

• Download the app form the website, its available for Windows, Mac, and Linux.
  
• Add your national or crypto currency accounts.
• Create new offer or take an existing one.
• Follow the user interface to finalize the trade.
  

It works perfectly. Try it.
