First thing I would recommend is adding some padding to even the space on the bottom of the navigation buttons, the text is too closed to the bottom.
The design has a few cool elements, not perfectly designed but still adds a little bit fun to the site. The fact that it's using a couple of icons on many sections of the site is great. On the blog section, make the articles a bit shorter by adding the "read more" because so much text there just makes most people dizzy and leave the page. Make the blog titles a little bit bigger.
About the content, I'm not a forex expert but I would have to say you have enough content, videos, and it's not bad at all.
Site purpose: 8/10
My Overall rating for this website is 6.6 out of a 10 point system being the best.
