All the other ones are closed to newcomers.
yea i recommend hitbtc, i recently used it last month and as i used it, it is easy to use and very reliable and secured, some exchanges is closed to new comers because of the over crowd of the community joining the exchanges, like bittrex, if your a new comer hitbtc is suitable for you.
I don't recommend using HitBTC because I think that they are using fake numbers on their website to cheat people of their coins. They just want them emails sent to them as if they didn't know what they were doing.
