I suppose it’s like anything, until there’s a compelling reason (ie a good or popular game (notice the differentiation)) to use it, then we’ll just slag it off as a gimmick, a con etc.
I’m starting as CTO tomorrow at a company that’s resurrecting a ‘90s football game as a cross-platform multiplayer football game, where you can trade players on the blockchain. Even now I’m not sure why’d you’d want to do that, but I can see it working within that sort of scenario, especially as player trading is something that’s done in “real” football.
I think Square bloke is right though, it’s going to happen, but the whole wallet/transaction process needs to be a to slicker. It’s much easier than it was 5 years ago, but it’s still a fair way to go before your Mum could use it.
