Hey fellas.
Recently, my friend introduced me crypto reward game, Rankingball.
Since i like to watch NBA, it was pretty fascinating that i could earn cryptos by choosing which players and
team will win a game while watching it at the same time.
Plus, i found that you can sell the cryptos on exchange. I forgot the exchange name lol
Anyway, if you like to watch NBA and earn crypto simultaneously, i think you should definitely check it out!
Which site you are talking into?
https://www.rankingball.iohttps://rankingball.com 
It looks like the .io domain, maybe the purpose of the OP, you can get through the rankingball site by collecting points that can be converted to RBG token and then you can sell them on the exchange, it looks like the tokens are listed on the coinbene exchange.
Honestly I never tried it, the token didn't appeal to me either.
