If I'm not mistaken, we are allowed to use one code once in each month and if we try to apply a fresh code, but our duration hasn't expired yet, we will get a message something like this> : "the maximum time to apply a code is already reached". Anyways, I wonder what happened to @8bet. It's been a while since they haven't posted a new code.
Did you find out what happened to 8bet by chance?
