What is the fastest way to earn money online?

1. Create an OnlyFans or YouTube account and share whatever you think other people are interested in paying / watch ads for.
2. Buy Crypto / NFT with the intention of selling it at a higher price (requires investment)
3. There are organisation paying you to watch and click on advertisement all day (you won't earn much).
4. Some online games have items that can be sold on eBay.

Thats all I've got. There is a documentary on Netflix called "How to sell drugs online fast" but i'd say it requires experience.
