Realistically, if you expect to make instant money with no investment, you are limited to offering time/skill not money or automation. Not being as cynical, here are a couple of things you can reasonably accomplish within 24 hours:
1. Offer manual gigs on forums or Discords. Join some SMM/cryptogamming/ gaming Discords and offer to do pretty basic stuff collecting data, DM management, simple content writing etc. People do pay for microtasks.
2. Post for people on Reddit/Quora
Sellers need upvoting, posting questions/answers or seeding discussions. If you have aged accounts, that’s a bonus if not post manually with new ones.
Any clue? Even if it’s obscure (how to fix a Telegram spam block, how to get free logos, etc.) convert that into a brief PDF and put it on a marketplace like Ko-fi, or pitch it here.
Don’t get sucked into the “push button” BS. You don’t make $5-$20 in a day pushing something unless you give people something worth that cost. Start with that.
