Ironfx has hooked by its reliability. CySEC is the organization that is well-known for traders and these guys have obtained this license.
Apart from that, they have numerous awards in various nominations and it's the very sign of the broker's fame.
AFAIK, they even take part in various contests like Fx EXPo in Dubai and all that.
I was hesitating before joined them, because I didn't really like the leverage that could be up to 1:1000. However... only after I researched conditions I understood that I could choose an account with a limited leverage to 1:200. This is the best match!
