I think you should go with 3 of them. Your profit could be multiples 3 but you will cost much more time

.
For me we can totally do it both, but if i will need to choose 1 which i more preffered i will definitely choose working on signagure campaign why? Because i am not very good on trading, just like i am not an expert or good in trading at all so i prefer working on signature campaign, and if we find a good campaign we can surely make manh profit from it.
