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.
