Yes the bonuses are for BitEdge referrals only so you have to sign up through a BitEdge referral link to get them. Some forums don't like people posting their referral links so I just posted the links to the bonus section of our site instead.
I have asked Stake to drop by here to clear up any doubts and I am sure they will soon.
So what about those who have existing accounts on stake ?
Is this offer only available for those who will create new account on stake.com and other sites listed with your referral link ?
I think those who have accounts on stake already won't be eligible to have this bonus. As op posted that you have to sign up through the referral link from bitedge since posting referral link here is not allowed. What about other person who will sign up through a referral link but not from bitedge but from other stake player.
