I'm newbie...!
For newbies, there is no use joining a signature campaign. Also, Bitcointalk is not to make money. People with quality posts, make it to the campaign. However, you can try to offer loan or try to invest in a currency asking help from good traders or you can use betting advises of tipsters or post your quality and ask payrates for them. Good luck, my friend!
but there are few campaigns that are allowing newbies to join them and if you are holding newbie account that doesn't mean that you don't hold any knowledge of bitcoin.
Yes there are some campaigns that accept newbie to join their signature campaigns but they have low pay rates with is not bad after all if youre looking a source of income.
Just continue to rank up just remember that dont spam on threads so that your journey on gaining on money on sig campaigns would not be destroyed because of spamming.
your right there are a few signature campaign allowing newbies rank but do not recommended to joined if do not have any knowledge of bitcoin or altcoin. maybe only spamming because they are do not know anything.
