We can't deny the fact that Bitcoin is a great companion when it comes to trade involving a lot of a variety of commodities, as the case maybe, but rarely physical.
Have you ever purchased a physical commodity using Bitcoin? What's your experience?
I have never purchased any physical goods with Bitcoin and that is not a problem for me because I can conveniently use fiat for it, besides most businesses don't accept cryptocurrency. Bitcoin don't need to be used as a currency for payment of goods and services to remain a store of value that is why it is there as an alternative to fiat for people that wants to spend it. Bitcoin adoption is increasing mostly because it is a profitable asset to hold, most holders will rather hodl it and use fiat for their payments. Hopefully in the future it will gain adoption to be used for payments of goods and services.
