As an experienced trader, it's not important to me how narrow broker's spread is. It's about how much I can trust company. And whether I can safely keep large amounts of money in my account.
I want to say that even if Defcofx has spread that is several points wider than other brokers, I will still choose this company because I'm confident in its reliability.
I carefully studied reputation of this company and those services that provide security.
This means that my money is safe here.
