My favorite privacy crypto project is Safex. It's a Monero fork that is building a world marketplace on the blockchain that will allow people to buy and sell with others at low cost and in privacy. Safex Cash (SFX) will be the currency used to buy things on the Safex World Marketplace. Sellers will be charged a flat fee of 5% to sell things on the marketplace.

Holders of Safex Token (SFT) can use their tokens to set up shops on the marketplace to sell their goods and/or stake their tokens. The 5% fee charged to sellers is put in a pool and then distributed pro rata to the holders of Safex Tokens who have staked their tokens.

The project has a great development team and the software is in the final stages of testing. You can go to Github and see all the progress. The marketplace is set to launch by the end of May.

Safex Token is up 85.6% relative to Bitcoin in the last three months, and Safex Cash is up 92.1% relative to Bitcoin during that same period, probably because investors are anticipating the launch of the marketplace.

The market cap of Safex Token is only about $9 million, so there's still plenty of upside. I think this is kind of like buying shares of Amazon or eBay before they launched their websites.

You can go to Safex.io if you want more information about the project.
