Tbh we are doing the same, accidentally, for the current referral rewards program. We could have just given all the proceedings to the top karma holders, but as the paper also concludes: > For existing NFT holders, the ongoing synthesis of new NFTs ensures that even top players cannot simply “rest on their laurels”; they must consistently contribute value to maintain their status This is also true if you want to participate in the referral rewards program. Either you are a top karma earner *of the week*, or you're directly referring someone. But we're not rewarding already retained users specifically, although we do indirectly, but we don't value seniorage.
