I bought SM with fiat ......
SM itself is a form of crypto. I am using it to invest in both the game itself and Steem.

To the best of my knowledge .... The $100 daily and $1000 weekly are free to enter for anyone who bought a starter pack. It might be a good idea to collect free cards from all the giveaways as who knows what they may be worth in the upcoming years. This game has huge potential.
