Word. I mean if a reputable site like stake, sportsbet.io, duelbits and so on would make this you can be sure you can actually get the reward but with a site like nitro I would always be very careful. Not the first time they would have gone back from their word in something promotion related, and certainly also not the last time I guess.
Truly just another blatant attempt to gain attention and bring people in, not more and not less.
