It is great to have posts like this, but i think you will be more lucky with a website, translated to english, instead of a post in bitcointalk, posts moves quickly to the depths of the forum, and will soon be forgoten.
I remember of some posts doing this, some was tracking dead coins and listing them (necronomicon), they all dissapeared because of lack of maintenance.

Your website looks great, but i don't read german, and it could be easily extended, you can also use a block explorer's API to get network hashrate instead of coinmarketcap, you will get more accurate.
