It's okay to try and pay attention to gathering referrals but I can't do anything or force them if they don't want to keep using it.  Honestly, I don't even know who the users I referred here are because we only see their BTC addy.  So far only one or two have remained active in my referrals out of 51 as I look at their recent activity.  It's also not easy to refer now because we know this platform has been around for a long time and we know that almost everyone in crypto has an account here except for beginners who don't know it yet.  Regarding Multiply BTC, you are in luck if you can find a real gambler who will deposit money here and play.  Even if you only have one referral as long as he uses this platform every day especially in gambling there is no doubt that it will give you a contribution to your income.  Maybe there's just no interest really, they don't know much about this industry or they don't have the patience to like the ones you put in here so they are no longer active.
