Always wanna create a site like coingecko or coinmarketcap. But does not know how and where to start. Even, does not calculate the budget. I need a figure or plan on how to start. Now things are seem complicating, does I need to learn basic web developments for management it.
Note: Not finding any developers.
You can start on Namecheap where you can buy a domain for your project and from there you can also purchase a web hosting plan they offer one of the cheapest plans in the industry,
Don't worry they have tutorials and articles on how to buy and launch your website and they have dedicated support.
Once you got these two, create an account on
