If you don’t have them, your chances are small unless you get into other options that are similar to trading and signature campaign. You can also do affiliate jobs, and one of the best sites I would recommend is Peerfly.
Even if you don't have any technical skills there is nothing to worry as you can learn trading any time and if you are good in it then you don't need to find many ways to earn bitcoins as only trading can give you best income regularly and signature campaign will be an added advantage.
