I think it would be best if the splinterlands team wouldn’t need to spend a lot of resources.
One idea would be to have a special Dec millionaire club with different levels. So 1 million gets you a discount on the store, 10 million get you a special nft and higher discount and 100 million gives access to the highest discount and gives guaranteed access to pre-sales along with the other benefits. The dec would be locked in a smart contract for a year.
A millionaire club for sps would be interesting as well
