Why can't I buy the game item with actual fiat currency (or its many non-crypto microcurrency equivalents like what MS and Sony operate for their stores)? They can also intermediate its authenticity and ownership between games.
This is how things work right now - there are lots of promos where some in-game addon or item is provided upon validating ownership of some other thing. All of the major stores (see: Steam, PS, Xbox) provide this functionality.
The only real difference here seems to be decentralization - but how does that benefit me as a consumer? I know there's a lot of words spewing around re: "authenticity", but I still fail to see the practical applications of a virtual hologram sticker on horse armor.
But this echoes my overall feelings about crypto - it presents many downsides and few upsides. The only consistent upside it provides is decentralization - but it's only an "upside" insofar as it is ideologically attractive to adherents. In nearly all cases the decentralization provides no tangible benefit to the bearer.
