I got a Level up bonus of around $900

is this a Small bettor? wagering half million dollars for single site ? lol you must be joking

Half million dollar wager is a lifetime funds for a normal person so having this for gambling is a lifetime achievement already.
and the reward is not bad , 900$ while you are ready to the next level

Congrats Man , you are really a good gambler.
Small or big is something personal, it can be something big for others but it can be something small for him. But I believe if you play regularly even you play small per bet, you'll reach that amount later. I'm also small gambler (smaller than roycilik obviously), and I'm now 20% left to reach the same level as him. Few days back his percentage to reach the Queen level was under me, but he seems that he wagered a lot in just few days so he reached the Queen level faster than me.
