AFAIK, their VIP system is simply identified by NFT, and does not take into account the user's betting record. The level of the NFT determines the VIP level, and if the NFT is traded to someone else, the VIP status is transferred as well. If you manage to upgrade the NFT to the highest level, you can directly exchange it for $70K, but the difficulty of achieving it is also evident.
It is my point to ask. Without condition of betting record, is only NFT card enough to approve VIP membership?
Users can sale off their NFT cards and that can help other users to have cheaper cost to own the VIP membership. $70k is a very expensive cost to own VIP NFT that can explain why SLM team did not mind to bind more conditions to their VIP membership.
Do they have different VIP membership levels and have ones that less expensive than $70k? I am still worrying if they have cheaper than $70k NFT?
