Blogging: Low costs but super competitive. It takes time to stand out and build traffic, especially in crowded niches.
YouTube: YouTube could be the best option. With a pre-monetized channel and a cash cow team, you can earn money with less effort.
Ecommerce: Requires more upfront investment (inventory, website, marketing) and can be time-consuming with order fulfillment and customer service.
I think YouTube is the easiest way to earn, especially if you can hire a team to handle content. It’s quicker and less work than blogging or ecommerce.
