All my competitors use the same link scheme if i add no-follow on those then i will have no hope to rank. But i still believe it may be something else and not the links. How can i be sure ?
I'm afraid you don't really understand how nofollow or linking works. Adding nofollow is not going to cause you to LOSE rank.
You can request a reconsideration in your Google Webmaster Tools account. That's the only way.
Again, what your competitors are doing is totally irrelevant. Concentrate on what YOU are doing, if you want to get out of the penalty box.
