If, like you say, the companies think or say they are using Bitcoin, that's factually incorrect given not s single person on Earth has ever saw Bitcoin. Bitcoin is a non-existent thing. Of course, you can still think and talk about bitcoin. Like you can talk about Zeus, flying spaghetti monster, unicorn, or whatever. But those are all fictional characters. And if you insist talking they are real that fits the definition of a delusional behavior.

Not a single person in the world has seen infrared light, yet it exists. You can measure it, it's not a made up thing. You use it every time you turn your TV on with your remote control, yet you don't see the infrared light between the two.
In a similar way, you can't see Bitcoin, but you can use it, it's as real as infrared light even though you can't see them.
