I have to admit that you've done a great job so far but there are room for improvements and after evaluating your website, these are what you should do in my opinion:
1. The logo of your website is a bit cut of in the lower part (circle part) so you might want to re-size it and upload it again although not that of a big deal
2. Not sure if your using a premium theme or a free one, either of which, it would be better to look for a better theme instead
3. In the footer area, you've mentioned "2016 Copyright, FirstForBitcoin. All rights reserved" second to last and have included BTC pop ad after it and they should change places since Copyright is always the last part
4. The comment system use, I assumed is the one that came with the theme and would advise to use another one (there are about 10 you could choose that are attractive and have more functionality)
5. On your Top 12 Faucets tab, the address bar is:
http://firstforbitcoin.com/top10faucets/ so you might want to change that
6. On your Top 12 Faucets page, it would be better to give some more information for each like max-min rewards, time intervals and etc...
7. ON your Bitcoin traders game, the image that is used is very bad and low quality and it should be re-design completely and also the UI is a bit out dated for that page
Regardless of those I mentioned, it really does have great potential to be right at the top so best of luck

Thanks for the detailed comments!
1. Thanks, I noticed the cut logo and will try to fix it asap.
2. I am actively looking for a more modern theme and speaking to a WP developer to implement over the next 2 months. Looking at the BE theme. Currently, I am using a paid version of the Synapse theme. It looked easier to use at the time.
3. Thanks for the tip. I might even remove the banner because I am not too sure how effective a banner right at the bottom of a page could be.
4. The comment system is "Disqus", it is not part of the theme. So far so good.
5. I was actually in process to change it to a top10 from a top12 and somehow never got round to it.
6. Good idea, thanks.
7. Yes, the image is real bad. I have someone looking at it to improve.
Appreciate your feedback!
