i dont know your skillset, i can just tell you what NOT to do:
- dont start any form of trading, if you dont know what you are doing its just socially accepted gambling
- dont put it aside or "invest" (no its not gonna grow into 1.000.000$ eloncoins)
1k is basically useless for building anything passive. if you have unlimited time, use that 1k to build a niche website / digital service + outreach.
practical examples: creating QR codes for barbers leading to their service page, Calling restaurants asking if they have a way for customers of reserving a table beforehand and if not building it for them, offering ultra small newb influencers likes and followers on instagram (you just buy from here, resell to them).
Theres billion things to do, just think of all the small things that could improve the local businesses around you on a day-to-day basis. None of that is really worth it tbh, but since you asked how to make more money online only thats what i would do.
