Thanks for mentioning OKX. I am using the exchange too and I check their convert page which let me know more about the reason the exchanges provide convert service for their customers. You can check this which is what I found on the convert page of OKX:




If you check 'no slippage'.

I noticed that it can be a good option for people that do not know much about spot trading but just having little knowledge or almost no knowledge about sport trading which requires more knowledge. With convert, anyone can easily convert from one coin to another.

The market price is good and the same as spot trading market price too, but with the benefit of zero trading fee. This is a good option for coins like bitcoin, ether and others that have high trading volume.

Because I see the simplicity of how to use the convert. I check the Binance lite and OKX lite which. See what I found:

Binance lite at the left while OKX lite at the right side

     

I press on the convert which is the only ways to trade on the lite version. The spot trading is only available on the pro version. I think convert is just for people that do kit want to learn much or go deeper into how to trade. Even a novice can easily use the convert to exchange from one coin to another.


About the convert on OKX, only market order option is available, unlike Binance convert that has both market and limit order option.
