Step-by-Step Guide: If you already had a Keybase account registered before this announcement, activate your Stellar wallet to claim your ~$20 worth of XLM which has already been airdropped to qualified Keybase accounts. If you are a new user, download the Keybase app, sign up, connect your Keybase account to a GitHub or HackerNews account that was registered before this announcement and activate your Stellar wallet to be eligible for the next monthly airdrop rounds. Free XLM will be credited to your Stellar wallet automatically on the 15th of each month if you are a qualifed user. Total airdrop value of each round will be divided equally among all participants. Unclaimed XLM from inactive wallets will be returned to the Stellar Development Foundation within around 6 months or so. See the official Keybase announcement and Stellar announcment postings for more details about this airdrop. If you own 10 XLM or more you can also take part in monthly staking airdrops by simply holding XLM in your Binance wallet. Fore more information about the Binance staking airdrops, see this post.
