Your website starts mining with visitor's CPU right away, without asking anything.
Just visited the link and I can confirm this.
So a word of caution: don't click on the website link.
The question is does the OP want to trick people into using their computer's CPU power without asking or not?
If the second is true, you should immediately make the necessary changes and ask for permission first!
Somehow I doubt that the intentions are honest. You have listed BTC, LTC as minable coins, which is out of the question for CPU mining even if you trick a lot of users into joining your program.
