For each of the options, feel free to leave a comment to describe your role in greater detail.
I'm looking forward to your replies!

Many factors to make money are related to Blockchain.
as an example:
I joined some Bounty or Airdrop Projects. And I made my wallet address using Blockchain. And I do not recommend to continue to trust the project to be run. You should check some projects run by the project manager.
