Did you get to play with more than 10 accounts? and have rented cards in the accounts to get to diamond or champion? played tournaments with multiple accounts? if not so then you could not make more than 300 usd a month playing, be people who are lucky and manage to make 1200 usd playing!
What are you talking about? For any game I've tried its restricted to use multi-accounts
There is a player who invested more than 200 thousand dollars, has a whole system of employees called th, play tournaments, rankean, do quest, that brings to him an amazing amount of constant money, I think he has more than 30 well-equipped accounts, the use of multi-accounts in that game is not punishable.
