Maybe because the system for rank used from total turnover of each player. So, even though we deposit a small amount, but the total bet achieved is quite large, then members with small deposits can reach the top 10. I was in the top 10 slots, at the beginning I registered in BK8, but at that time I won quite a lot, so my turnover was also high because I played intensively. but now, in slots alone the top 10 has reached IDR 1 billion, as far as I remember the top 10 was only around 700 million.
