It contains instructions for redeeming a crypto airdrop for github user who in 2019 had

(1) Around 15+ followers on github
(2) A public key added to their github

It is currently valued at around $2000 USD, and can be sold on a crypto exchange, converted into crypto-currency, etc.

The instructions and airdrop are legitimate, but I have problems trusting third-party code with my private key.
