Looking at the image shared by ryzaadit after your post, I guess this $5 exclusive bonus started by duelbits this year. So perhaps this bonus is for those who have good activity since the beginning of 2022.
I'm not complaining either. I was just curious on how was they selected those users that will receive these exclusive bonuses. And I am glad that you was able to give the answer which satisfied my curiosity towards the bonus. Thanks!
I remember I received my first $5 exclusive bonus email during February right after I become inactive playing in Duelbits after I participate on christmas event. And I keep receiving this same email every month until the Eastern Egg hunt event because that is the time I become active again on Duelbits to claim the 5$ bonus and daily Egg hunt reward.

I see. I also participated last Christmas event on Duelbits. But that time I wasn't able to wager that much. If I remember it correctly, my ticket entry for the raffle was only around 50 tickets. Until then I rarely play.
