Signature campaign can really give you the steady income especially for the higher ranks and for me this is the easiest way. For just posting and joining dicussions you could already earn money plus the learnings you will acquire about crypto world.
Yes, but I think only enough to buy a cup coffee and a box cigarettes (if legendary level), it is impossible we can get rich from signature campaign, I think the best way is by mining.
Signature Campaigns are proven to give steady income but is is neither the best nor the easiest way to earn income by Bitcoin. Also you can see that signature camapaign tend to be strict nowadays rendering you sometimes with lower pay or nothing at all. Which means they are strict about the quality of your posts.
