Bitcoin was envisioned as a “peer-to-peer electronic cash system” in Satoshi Nakamoto’s original 2008 white paper, and one of its biggest appeals was frictionless international payments. Bitcoin promised shorter transfer times and lower transfer fees than you’d get at Western Union or another money transfer business, the de facto option for sending money abroad.

But 10 years later, Western Union has been unfazed and unaffected by bitcoin.

In fact, profits at the world’s largest money transfer company are up: for Q3 2017 Western Union reported a 13% year-over-year increase in earnings per share, beating analyst expectations.

Considering that Western Union has been around since 1851, it may look like an old-guard, outdated company ripe for disruption, rooted in brick and mortar. It still has 550,000 physical locations globally (a staggering figure, but remember that many of these are small counters inside a grocery store).

But the company has quietly gone more digital, and specifically more mobile. Western Union integrated with new mobile pay options like Apple Pay, Facebook Messenger, and Tencent’s WeChat Pay. And as Fortune reported in November, more than 60% of Western Union’s digital transactions now originate from a mobile device. Its rails handle $150 billion in transactions per year.

None of those transactions involve cryptocurrencies; Western Union doesn’t allow them.

In December, the company made a little bit of noise in the bitcoin world when a Reddit user posted the message that Western Union gave in blocking a wire payment sent to the bitcoin exchange Kraken: “Please be advised that we have determined your transaction is related to cryptocurrencies. This is one of the purposes of trading that we do not allow as per our internal regulations, which is why the transaction cannot be processed and the funds will be returned back to your bank account in full.” (Western Union declined to comment for this story beyond confirming that it does not allow cryptocurrency transactions.)

This wasn’t the first time that the money transfer giant has targeted cryptocurrency. In February 2017, Western Union posted a video interview with its CTO David Thompson to its corporate blog, called “Is bitcoin a viable currency?”

Surprise: Western Union’s opinion is “no.”

Thompson’s description of bitcoin, in which he compares it to a bag of corn, raised some eyebrows in the cryptocurrency community: “Think of [cryptocurrencies] as a bag of corn, or silver—a commodity that you can exchange for a service or a product,” Thompson said. “Cryptocurrencies confuse a lot of people because they aren’t fiat currencies… So for example, if you want to go get a car wash, I don’t think your car wash is going to accept a commodity like a bag of corn. They want fiat currency.”
