I am interested with the free rolls, I think it's going to be a bigger chances of earning a capital bets for game while you don't have funds yet. However the game can only be appreciated when playing at pc, because mobile version isn't yet available and I can't see any mobile app for convenient betting.
Many people interested with freeroll especially those who want to try the game for free while they have the chance to win something for free.
I myself do not really like freeroll as most freeroll has low prizepool and it does not worth the time I need to spend for the freeroll.
I would prefer to see something like GTD tournament where players need to pay buy in tickets for it and the site add some amount of money on the prizepool.
