In my case, apart from the signature campaign, I also make some money every month playing poker. I don't win exorbitant amounts of money but it's something like a side hussle that gives me extra income. Then what I do is that the money I earn I invest it. The poker money goes into an index fund, and what I earn in the signature campaigns I save almost all of it.
Well, that explains your username (lol). Assuming you're pretty good at poker, it sounds like you've got a smart plan in place. And assuming you're young, all of that saving should serve you well in the future. That's one of the things I wish I'd done when I was a much younger man--started investing in the stock market and/or saving cash. It's also smart of you to invest in an index fund rather than trying to pick your own stocks, because the latter usually causes you to underperform the market (unless you're
really good at picking stocks, which most people are not).
Earning from signature campaigns is good while it lasts, but a lot of members here--particularly new ones who came here to participate in bounties--don't seem to realize that it's not meant to replace real-life earnings. Granted it looks like they're not going away anytime soon, but there's no guarantee that campaigns and bounties are going to be around forever. For a while after the ICO boom, there were very few sig campaigns and competition to get into the ones that existed was fierce. And right now I don't think most of them pay as much as they used to.
Take Chipmixer; 50 posts/week used to get a participant 0.0375
BTC. Now 50 posts is worth $300 max. That isn't bad at all and I'm not complaining, considering that all you have to do is make 50 posts in a week, but my point is that the rate has dropped significantly, and I believe that's true of other campaigns as well (please correct me if I'm wrong).
By the way, OP, I think most members of this forum are earning money online. At the very least most of them are in a campaign or bounty, and I'm sure a lot of them have side hustles like Poker Player mentioned--trading, or gambling, or doing various jobs for hire.
If I'm not mistaken, Chipmixer is paying $6 per post, while having no minimum requirement for each week, right? Probably one of the highest paying campaign, you can easily receive an average of $200 per week.
There's no minimum, and there's a max of 50 posts/week as I mentioned, so you can earn up to $300/week.
Edit: Oh, by the way: the most exclusive campaign on the forum has got to be Foxpup's Merit Cycling Club, by invitation only. Very hush-hush, like the Skull-and-Bones Society.
