Exactly. I have noticed this several times. Presumably this is one of the many reasons why most governments have not very well classified what Bitcoin is up to now. But you know, being that they are in power, they can always make a classification as to what Bitcoin is, along with all other cryptocurrencies. It is just that to me Bitcoin seems like a combination of all those types of investments due to its general makeup- price, characteristics, features, selling point, among others. And if you look closely, you can say it can be classified as an asset rather than a payment system to which it purports to be. It is truly confusing but what is making things worse is the fact that most governments shun away from Bitcoin by not categorically defining it nor outrightly banning it. Seems to me they are just being lax about it like as if nothing is supposed to be a problem.
Bitcoin is a beast on its own and therefore it cannot be classified. It's everything and nothing at the same time: remember bitcoin don't exist, they are simple entries in a ledger. We control keys not bitcoins. And so on...
