Online can be capital intensive, depending on the kind of business you want to start, for example if you want to start an ecommerce store you will have to account for inventory, Shopify monthly fee, design and development few, whereas if you're just starting a blog you only need to buy a domain and hosting to get started.
It depends on what you want to start and the resources you have available, but whatever you plan on starting, it's better to start small and make sure you're guided by what people want, for example instead of starting an ecommerce store you can start selling on Facebook and grow from there.
