Have fantasy sports massively impacted traditional gambling?
Here where I live traditional gambling isn't big to begin with as gambling is not legal in the country (in few states it's legal, but largely it's not) while fantasy sports is legal in the country and everyone is playing it — and I am not exaggerating with 'everyone' word here.
...The benefit here is you do not even need to risk real money in fantasy sports.
We have variety of fantasy sports apps here, and to win real money you do need to join leagues involving real money.
...Another question people ask is whether what would fantasy sports be considered as... gambling or gaming?
Again it requires real money to join leagues, and you can lose this money, so I consider it a gambling.
