Here is a very short article, with instructions on how to earn ETH and Devcash on the Devcash Bounty Platform. You can earn either ETH or Devcash by hunting bounties.
Go to https://bdu.dev
Sign in using Metamask, Portis or Authereum wallets
Explore the bounties. You can see the bounty description, what the tasks are, the reward, how many bounties there are, etc
Select a bounty and then click Hunt Bounty
Write your submission in the submission form
Click submit and approve the transaction
Wait for approval, and check back to see if you got your reward!
I hope this helps you navigate your way through the Devcash Bounty Platform. May you have good fortune in your bounty hunting!
