Stellar by Keybase Airdrop

Keybase is a free, secure alternative to Slack, WhatsApp, Telegram, and other chat apps. It supports groups big and small, communities, and teams. Inside Keybase, all chats are end-to-end encrypted. Imagine if someone broke into Slack’s servers and stole and published your company’s or family’s messages? It would be devastating. Keybase’s encryption makes a cloud break-in impossible.

And because Keybase is powered by public key technology, it also can understand cryptocurrencies. So all you have to do is install the app, and you can register for the free Lumens.
