Due to the many cryptokitty clones and the current uphill battle for Cryptocurrency, I am going to be more wary of investing in Crypto-gaming. However, giveaways are the exception. By providing hype and giving some users the chance to try the game out, they are hoping you would like the game and stay. I see no harm in that. If you want to sign up for the giveaway, please visit their site at https://www.everdragons.com/ and maybe check out some of their videos.
