There is no difference between the two sites.
Both sites are maintained by separate teams, we have an alike layout, but the contents (events, payments, bonuses, creatives, affiliates, etc.) - they are different.
my question is simple:
do these two sites belong to the same person?
I've read around here that even the wallet addresses for payments and deposits are the same address, I remember commenting on this, and at the time I wondered how it was possible that unknown sites share the same deposit and payments address if the owners are not the same? Of course the claim that the owners won't be the same was someone's statement in this thread (I can't remember who said that anymore)
