I am thinking to start own exchange website like (coinexchange.io) , yes I want to build small exchange.
But before start I want to know something , hope I will get my answer.
Building exchange is profitable?
How much investment it's need?
Where I can promote it?
How I can avoid or put low transaction cost?
How much time I need per day behind this project?
If you want to share any suggestions then most welcome.
You cannot make an exchange website by yourself, in order to do so you have to gather a good team before anything else, there will be a big workload in order to start an coin exchange business. If ever you have gather a good team, they can answer your questions for you actually since for sure they know how it should be done, and better to do research with them.
