Too Long; Didn't Read
I started playing Gods Unchained on 4/8/2020. It's that specific because that's when I purchased my first card for that game, as verified by Etherscan. The ultimate goal of the game is to find rare items to boost your character or find better loot. The digital currency that's very liquid (ETH) and not the in-game currency (ETH), is able to resell the card back using the marketplace if I choose to. Authenticity is simply verifiable proof of something is what it says it is, with something is verifiable.
