As we know, it's hard to join a bitcoin-based signature campaign posted in the "services" section. As seen, there are plenty of altcoin bounties that most forum users are trying to participate. Can you say that these campaigns are profitable? Or have you had the chance to join a signature campaign (altcoin bounty) that you found very lucrative in the past?
I dont think is hard at all for those who have a decent understanding of how bitcoin works and knows how to keep their head cool. Besides if you dont have a flair for writing, this type of hobbies will take up a lot more time and pressure on your head.
While there are many users who join altcoin paying campaigns, I am sure you can go around asking, most of them have not been happy with the delays in payments, lack of pay security and the uncertainty regarding the price and dumping on exchanges. Often the entire project might get abandoned and you will be left with a bag of shitcoins. I have joined a few bounties in the past besides a running signature campaign and my experience has been little worth sharing.
So I would suggest you to get a better understanding of how to write in the global threads and then apply for bitcoin paying campaigns, because these are the gold-standard of campaigns here.
