Is there something that might not allow me to abuse referral program? Why not to create 10 ETH wallets, first account and invite the second, third... why does one could not try using this chance to make +5-10% more?
Hm.. Quite reasonable question, because everyone can do that. Yes its not convenient, but really profitable, its worth making a little effort.
Is there exact chance / probability for jackpot by the way?
