There's no easiest. Every work needs effort. It's like earning fiat money.

If you have the skills to offer, try to post it on the Service section of the forum. What are these skills? Mainly office-related skills, photoshop, image-related modification, programmer, etc. Or if no demand, offer it outside crypto and accept fiat payments instead.

You can also consider understanding the art of doing trades. It will take time to learn it but if you are serious, shouldn't be that difficult to understand the basics.
