This thread is so timely, the longevity of any firm in business spells credibility, trust and breeds confidence. You always have this calm feeling when working with them because you know they've been in the business for long, same applies to brokers.
One should definitely add this to factors they consider before choosing a broker. In my case, even after making sure of every other thing, I checked how long Forexchief have been in business before I opened an account and it turned out they've been around since 2014.
