@lupandina poloniex was my first choice too for exchange. But i cant seem to verify my account there and I never bothered contacting the cs as i have heard they never respond back well at least now i know it takes about 4 months. Good to know theres still some life forms going on in there
i like binance for the friendly user interface too and because they have app unlike many other exchange site. Ez to use and their support responded to me literally after 10 mins of my email.
However, the site is fairly new so im not expecting it to be as secured as the old ones..
