That's right and even if a token might sometimes have a big value doesn't mean is the same thing as Bitcoin because we are looking at two things here which one is dependent and the second independent and the only independent one here is Bitcoin, so actually I think Op understand and categories it based on value. However there is no much big deal when companies buys Bitcoin aside from the positive significant it will make on the price because what they are doing is to send some of there assets to were it will grow multiple overtime, although some of them might be buying Bitcoin to use it as a means of payment on there companies.
