In US is it ilegal to organize paid tournaments, or just online tournaments? Or none of the above?
Under the Wire act it is illegal to place bets or assist in the placement of bets over interstate(within the usa) or international (to the usa) via a wire.
The Wire act is federal, which means all of the US with some exceptions mainly horse and tribal casinos (which is still unclear). Each state has their own laws regarding gambling of any type. Some states have specific laws prohibiting interent gambling and one of the casinos listed them but I can’t remember which one it was. Some states do not allow gambling of any kind, even land casinos.
for their income protectionism
Republicans protect money, that ‘s what they do, that’s all they do.
