Well, i am waiting for one day toribash brazil players can buy boosters and toricredits using the mobile or paying in a lottery. What do you guys think?

Onebip have recently added another 14 countries to their list. Basically if they don't support the country, we can't sell to it.

But.. Brazil aren't in the list. Can't you make a exception and add this country?

this is already exists rubenoel . Go to the First Surveys Page ,and there have a little ToriCredits/Money calculator, where did he calc how much costs an amount of TC. Paypal now accepts Visa, very used in Brasil/Brazil.

You can try it, or PM Psytrance, a brazilian user who use Paypal and sell TC cheap.

With he,In brazilian money:
100000TC(100k)=R$15,00

In the official Toribash Website, In brazilian money:
10000TC(10k)=R$16,54

Cheap, better and safe =D

But how i will do it? i don't have 18 years old to use paypal, my only payment mode is paying at lottery

No. Onebip make exceptions, not Nabi. They can only offer this service to pre-approved countries from the list.

Why they can't add brazil to their list? They will get more sells and will earn even more

We can't answer for a third party. I suppose they don't think adding Brazil will pay off.
