Why not? I hope you make your exchange and hope it brings not only great reward and great profit to you but it also provides a great service to the end users (customers)
You did not state the reasons you trade on the your preferred exchange. Could you elaborate?
I use any cryptocurrency exchange that I can. Currently I am fairly limited in my options, due to racist exchanges illegally banning certain countries without the proper jurisdiction to do so. I agree that yobit is a scam, since they do not allow withdrawing of cryptocurrency coins to external addresses, as well as the support failing to fix withdraw issue resulting in the loss of funds.
Currently I am expanding my options by using smaller cryptocurrency exchanges such as
https://exchange.thecoin.pw/ Although many do not trust exchanges like this one, I do trust them. Also, I have gotten some killer deals when someone has sold many coins for virtually nothing.
One day I WILL make my own really great exchange from scratch, it will host all my cryptocurrencies and many more. I will never delist coins, and It will become one of the largest and most trustworthy secure trading platforms on the planet... Someday.
