Every article regarding cryptocurrency (this one included) refers to the product as a "currency," but it seems like that use case has been abandoned. It is strictly an investment commodity, like oil futures.
Bitcoin was popularized with the internet black markets, with purchasing drugs and prostitutes. Is that still happening? Years back I started seeing posts about graphic designers who would accept payment in bitcoin. Weeks ago I saw that there were cryptocurrency machines set up in Schiphol airport, where you can convert euros to bitcoins.
Discussions now are about which coin to invest in. There is little interest in buying coffee or lambos, just interest in how to maximize my (real-world, real-currency) money.
