That is true for the splinterlands paying for them. It kind of makes sense since you really can't start playing the game till you buy a spell book which is $10 in itself. That's most likely how the cover the initial RC that a new account needs which is pretty dang cool in itself. DEC I think is hive and Binance and SPS is Binance primarily. Either way it does help the ecosystem just not as much as it could. Not complaining though lol
