Your login page should have a link to the registration page. I clicked "My Account" hoping to be able to register there, and it brought up the login screen. Most sites have something like "Register now", instead of "Main Page". Your register tab has a link to Login, so why not the other way around?
Translations need a bit of work, like this:
Something better could be
Registration successful, activation mail sent. Please check your email to activate your account!
I also think you should you a color that isn't red, as red usually indicates failure (at least when signing up). I know red is a lucky color in China, but green might be better.
Your activation email should have a English translation, or at least have your site detect the language the user is on and send the respective email. Translations need some work too, as the subject is "Welcome to darkstarftw@protonmail.com! You have just registered your POW88.COM account!" I'd suggest removing the "to", as it makes no sense.
I think "Initiate questions" should be changed to something more obvious ("Live support" maybe?). I was confused to what it was until I clicked it.
You also have a few spelling mistakes (see red lines)
I noticed that your <title> tags aren't translated when switching languages.
Finally, for the personal info thing, you should put the actual labels on the left of the box, or as faded text where the text would be entered. People tend to read left to right, so they would see the empty boxes first, be confused about them, and then realize what it is.
Do you have proof of mining or a public mining address? I couldn't find anything in the FAQ.
