The website layout is simple and I like that. You don't need a fancy layout to have a great website. Well done.
I do have one suggestion: try to decrease the loading time on the Coin Listing pages. It took me 27 seconds to load
http://cryptodatabase.net/coins-b, which is way to long. I doubt that people would want to wait that long. You might want to try out
Cloudflare, it's free and it caches webpages for you (amongst other things), which makes everything a lot faster.
Thank you for your suggestion, I have implemented CloudFlare on top of my built in cache script I added. This may or may not help any though as the page load times is not caused by my server but rather from the mass amount of api calls the page makes to pull the coin trading information.
If I remove the coin trading information then the page will load almost instantly, 0.004 seconds on average.
However, I am working on an update but it is going to take me quite a while by myself to solve this issue. I am going to make a page for each coin that displays the information I already have and then the rest of the coin information.
Like my old version of the site,
http://cryptodatabase.net/oldThis is a lot of work though so it will be a while before its done.
