After watching @crimsonclad's presentation about the NFT showroom during Hivefest it got me thinking again about how NFT's are taking off these days and how I haven't really put anytime into looking into them

Splinterlands cards is a good start. Splinterlands is a good game on the Hive blockchain. You can use your cards in battles. You can even rent (or lease) (or even delegate) cards to/from other people. You earn a certain amount of Dark Energy Crystals (DEC) for every win.
