Stellar Lumens Biggest Airdrop of all time

Stellar is an open-source, decentralized protocol for digital currency to fiat currency transfers which allows cross-border transactions between any pair of currencies. The Stellar protocol is supported by a nonprofit, the Stellar Development Foundation.

The Stellar Development Foundation is airdropping a total of 2 billion Lumens (around $121 million USD right now) to qualified Keybase accounts (a free, secure alternative to Slack, WhatsApp, Telegram, and other chat apps) over the next 20 months. To be eligible for the airdrop you must have a Keybase account registered before the airdrop announcement OR if you’re new to Keybase, you must connect your Keybase account to a GitHub or HackerNews account that was registered before the airdrop announcement. This is to prevent bot signups to Keybase. First airdrop of 100 million Lumens (worth ~$6 million USD) has already been sent out sent to around 300,000 Keybase users. Upcoming airdrops will be distributed equally among all qualified participants on the 15th of each month, start from Oct 15, 2019.
