ah that argument, I read that recently, those are skeumorphs, here is a quote
> When it comes to this asset class, there are still people that argue against the concept of Bitcoin, mostly in reaction to one of its sales pitches without ever noticing what this really is. For example, people are likely to debate about the “coin” or “currency” nomenclature of “bitcoin” and “cryptocurrency” respectively. Ultimately, what we have is an asset with a fixed known supply, which has some attributes of all other asset classes, some improvements, is continually updated to have more attributes and improvements, in a world with massive inflation. This is the macro story of bitcoin, the big picture.
You might begin to notice that I use the term "digital asset" and "crypto" in its new asset-based context very reliably. It can be transferred peer to peer and I frequently do that, I don't use the term currency and I typically don't single bitcoin out specifically as I'm not usually talking about bitcoin specifically.
