If are just thinking that you are just collecting while you are posting and learn every time your read new threads every day its worth it. but you are thinking that you need to live with bitcoin signature campaign is not enought to liive with bitcoin.. better to find other source just like trading and or start your own business online..
Not everyone has the money to start his own online business or even trading. Sure, signature campaigns aren't enough to make a living with bitcoin. But it's totally worth the time because you can earn a lot out of replying in threads in this forum. You don't have to find another source of income, you have to
add another source of income. Rich people have 7 sources of income in average. There are some people here who makes a lot of money out of signature campaign by making an alt. Pretty sure they are trying to save money to start something else.
Having an alts in different campaigns multiplies your earnings. If you're going to ask why you should enroll your alt in a different campaign, it's because campaigns aren't here forever. If your accounts are all in the same campaign, if that campaign closes, you will have a hard time to migrate into another campaign all of your accounts. I don't advise having alt accounts though especially if you can't even manage to post constructive posts in a single account or if you can't even reach the maximum posts per week.
