use 1 hour for campaign. Just 2 hour per day
2 hours is not enough, reading some altcoins and analyze them if they are really good takes about 1 hour, but trading takes a lot of time especially when you are holding many coins. Signature campaign takes about 3 hours regarding on how many posts you will do per day. You're in a good shape if you don't have work in the real world, you can do a full 16hours of work in Bitcointalk, but if you are out of time because of responsibilities, other jobs then you must do everything on time and diligently enough to finish all the jobs.
