Most of the people are replying here without reading the full post of OP. The OP hasn't said that he/she has a top rank VIP account. OP has Bronze VIP rank account at Stake and Hunter VIP rank account on Wolf. Only $10k wager is required to reach those level. And he/she got the VIP rank advantages on BC.game for having good rank in Luckygames casino. In OP's view, mature account means an old account with any VIP rank. OP isn't a high roller with big bankroll. I'm not sure why some of you are addressing him as a high roller with good bankroll.
in my case I started in BC with lvl 30, this is because I transferred the lvl I had in Luckygames to BC, with respect to Stake and Wolf I can tell you that these last 2 casinos have a very similar VIP program if we talk about the amounts bet they ask you to reach each rank, in Stake you reach the Bronze rank with 10k usd bet and in Wolf you reach the Hunter rank with 10k usd bet. in Stake I have a bronze rank and in Wolf I have a hunter rank.
Moreover, OP's bankroll is very low and he/she prefer to hunt different bonuses to make it withdrawable.
Thanks for your clarification, it is true that I am not a high roller and I told this to another user who commented on the post.
