I am looking to try out a bounty campaign using signature but I don't see anyone worth my time right now, I do have a question about this, does it make more sense to promote projects that are already trading over those that are not listed on exchange yet? I see so many that aren't listed like whsiperMSG, Valore, Elysian Finance, they don't look like they will be hitting an exchange any time soon.
What and what makes you promote a project?.
You would be only wasting your time if you join a random project and they pay using their own token. But the time you will receive the tokens and be able to sell, they will worth peanuts. Almost nothing. If they pay in some well known currency, then yeah, you can take it. Not sure what you think it is "not worth your time". Just add it to the signature, and make contribute to the forum by making posts as usual. You don't lose anything here.
