What's actually trending now is signature campaign and this has now been a full-time job for alot of members from BTT and more also coming at ALT.
It can be one of the possible ways to make more money but considering it as a full-time job, that would be hard. A lot have always been saying even in other forum, that people should not use signature campaigns as a full-time job, they even insist on always saying to find a real job. It's not bad to make another way to make money like a signature campaign, but having a regular job as your full-time job is better.
A signature campaign is not the same as another full-time job where you can secure yourself even if it is for 5 to 10 years working in the same company. There are signature campaigns that suddenly ended, have an issue, or anything that bad happens that no one expected.
If you treat it as a full-time job and this happens, that would be an extremely hard situation.
