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.
Participating on a signature campaign is a good option ,you only need to post constructive and periodically in each day. usually weekly earnings will be paid by manager. and it was included in steady earnings.
It is a steady earning I agree. However many people here get greedy and end up spamming the entire forum. This is detrimental to both the users and the forum and a big headache for the moderators. Hence not everyone should get into it unless they have had a first hand experience in the forum yet.
Getting a job that pays you in bitcoin - freelancing for such work is the best way for a steady income. You can always supplement this earning with signature campaigns and trading income.
