Yes, you may begin by buying Bitcoin through a centralized crypto exchange. Centralized crypto exchanges act as an intermediary between a buyer and a seller and make money through transaction fees. Most people think that a centralized crypto exchange offers crypto trading. However, centralized crypto exchanges provide a wide range of extra features, including customer support and account services.

https://koinbx.com The title of the thread seems like a question as if the OP is seeking where to buy bitcoin. But in the body of the thread, OP started discussing how to use CEX and the importance of CEX. But in all what OP wanted to achieve is to promote their exchange.
I can honestly say that this is not the best way to introduce an exchange to the forum users.
The exchange and mixer business is rampant and also a competitive niche, someone introducing such a project should be able to state something different that the project offers rather than the generally known ones that could be seen in all other exchanges. If you do exactly what Binance do, why should I leave reputable Binance to uncertain you?
