I would say, the best is ecommerce. Because you can start from scratch easily. Best scenario: Sit at home, wait $ to come. If you sell virtual items, you don't even have to pack.
I would recommend you to do a research and understand how online business works. There are more scams and if you are new, you can easily get cheated.
The best business would be everything that people needs to buy. Not only wants. Something important and could last longer. Also you may try what you're really into, I mean what interests you.
Here all ideas are great but for me start blogging first & make money from Adsense then Start selling amazone products.
Hello, Any types of online business is good. But you can interest which types of business so easily do online business.
