Promotional efforts in crypto are pretty hard at the moment. A lot of teams turn to random airdrops, but that only works if you're past ICO, and to be honest, does it really work?

For the next week or so, The Co-fe Project has teamed up with NextStopMoon Designs to offer a free high-quality, print-ready PDF of their Bitcoin Whitepaper. I have one hanging in my workspace right now, and trust me, it looks pretty epic.
Co-fe is a blockchain start-up aiming to use the blockchain to create a coffee supply chain without farmer exploitation. Fair-trade organisations haven't done what they intended, but the transparency of the blockchain can bring a whole new perspective to fair-trade.
