ADante brushed this topic once with me on a past case we talked about, and if my memory serves me right, the situation with $Jack is like uhh... Freebitco with FUNToken or something? Where they're not really the casino's in-platform currency, but rather a project they endorsed. I'll perform blood ritual and summon ADante here.
He hopefully could give us a better insight on how $Jack and FJ correlates... [correlated?]
