That article gets its facts wrong, so I question its assumptions and predictions too.

It claims that KrsiFlyer is becoming a cryptocurrecny, but the article that it links to (when saying that) says only that KrisFlyer has a private blockchain and it's only used for redeeming KrisFlyer miles on the ground at retail merchants, it's not used overall for earning and redeeming for airline flights. So it's not all of KrisFlyer that become a cryptocurrency, it's a block-chain (the same technology used in cryptocurrency) being used in a different way for a new purpose.

Just because something uses blockchain technology for one aspect, that doesn't mean the whole thing is cryptocurrency! Blockchains are used in way more than cryptocurrencies, and it's silly to assume that just because a miles or points program uses blockchains for something that it's turned into a cyrptoccurrecy, in the sense that the term "cryptocurrency" is typically used to describe openly-traded currencies using blockchains.

So miles and points programs perhaps using blockchains more in the future for something? Sure! It's basically a more-secure technology for certain things. But airlines and hotels giving up control of them to make them openly-traded cryptocurrenices? I doubt it.

Of course, since no one stopped Capital One for calling their cashback points "miles", someone independent of airlines and hotels may someday claim to create an independent cyrptocurrency they'll call "miles". But they wouldn't be "miles" any more than Capital One "miles" are.

How many more silly articles are we going have that assume that anything using a blockchain is a cryptocurrency?
