This is about as solid a plan as I've heard around this game and crypto in general recently. Just for some perspective to the newer players, the game started in mid 2018 just in time for a pretty big, but brief run up in the broader crypto markets and then it was just about 2 years of down markets and cheap prices on game assets. At the time I just enjoyed playing the game and liked the team's vision so I played and stacked my collection sort of by accident without thinking it would turn into what it has today.
If you enjoy playing these sorts of card games this is probably the best place in the crypto markets to be putting your time & attention. $500-$600 worth of packs or select cards to play with and start earning the game rewards (SPS, DEC, Reward Cards) over time could grow into something very special.
