I define a good exchange in two ways...According to Design of the Exchange:
I have heard an experience that I wanted to use an exchange that was recommended to be because it was very secured, when I logged into the exchange, I couldn't navigate the exchange to convert or trade coins. I was obviously lost, it is not because I am new to using exchanges because I have been using them for long.
It is because the design of the site was not
User Friendly. I love it simple and unique and not to be obsessed by too many colours. With that I am comfortable with the design.
Secondly, the reputation of the exchange. I cannot have coins in an exchange and be finding it difficult to sleep because the coin is not safe or because I pressume that the coin is not safe. When an exchange is very secure, it will have good reputation in the future. That is why is stick to binance.
We know that setting up your own exchange is no joke and there is a lot to submit to the government agency, and it also requires a large amount of money before you can operate. And he can't handle it alone of course.
But I don't think he has made his own exchange yet because if he has one, he will immediately announce it here on the forum in my opinion.
If you read what he said you will observe that he said that he is a full stack developer, which means he is able to work on both front-end and back end. This means it will not be a problem to develop the exchange with his team and if he has a lawyer, all the paper works won't be difficult depending on the country he resides.
