Earn Bitcoins fast and free is a not so easy. Gambling is way to earn fast bitcoins but not Free. You may end up losing all. You signature campaign is a free method to earn coins, but is not so fast earning. So there is trade off between fast and free.
I will clear some misconception you guys are spouting. Listen:
1. First of all what exactly is FREE gambling? Are you talking about freerolls, promotions of some sort etc.? Last time I was checking these were not exactly 'free' money for gambling.
There is always some hidden catch with 'free' money for gambling. For example you have to deposit $xx first and do xxx rolls then - and finally you can withdrawn your money.
2. How the hell you can tell us that signature campaign is 'free' method. It is time consuming work, not something you do do easy and fast without effort.
That is - if you are actually think what you are posting, and not repeating short sentences about 'free gambling' or some other weird theories.
