From my point of view, in my beginnings my first account was made in Bittrex and I really liked it, also when I met Binance it caught my attention much more, besides that Binance has much more volume than Bittrex there was something that disappointed me about Bittrex , is that it banned the country where I reside, and it seemed in very bad taste because this is crypto, there should be no prohibitions for countries, however Binance did not do it and that generates confidence for those countries that handle considerable volumes of Bitcoin trading.
