https://www.theatlantic.com/business/archive/2013/04/bitcoin-is-no-longer-a-currency/274859/An article from The Atlantic magazine - from 2013, way back in 2013 - declaring that bitcoin is not a currency, but "the ultimate tech stock"!
The four years since the article was written has proven that bitcoin is akin to an Amazon or Facebook (stock, not company), and much less "Pets.com". That's a good thing.
I have to agree with them. Every week that passes without a new company in any local metropolitan area deciding to accept bitcoin as currency is a two weeks further away from bitcoin actually being adopted, mainstream, as a currency.
Bitcoin is an investment. A stock or an asset class/commodity can be debated, although it doesn't much matter. Bitcoin is a store of value not a medium of exchange.
What do you think?
IMO, BTC is a currency, an asset, and a payment method. Therefore, it needs to be analyzed by this threefold view. For now, the more preeminent side of it is the "stock" or asset side of it, as a token of value that is increasing in price because of the rising demand. But we can't forget the other two if we want to see BTC achieving its full potential.
