For me, it has to be SAFEX.

Privacy coin, about to launch on its own blockchain in the next couple of months.

The highlights, once launched:

- Built-in marketplace with a 5% commission fee
- Ability to trade anonymously
- Dividend payments (of the commission fees) to token holders who stake their tokens.
- Safex Cash, the currency of the marketplace, will be ASIC resistant, and has a revolutionary emission curve designed to match usage uptake of the marketplace

Much much, more.

As always, do your own research, but I recommend you research SAFEX.
