The public release with Binance planned on 15th June when competition will be started. Probably binance will be added a bit earlier.
I used to trade on a Bitfinex but for some reasons I moved to a fresh and young Binance exchange. Glad to hear that I could try my best now with Membrana.
Binance is damn awesome. I have deep respect for the guy who founded it and turned it into this massive business in no time. Awesome exchange for sure!
