Bitcoin is a peer-to-peer electronic currency, just like Satoshi said. When people start calling it something else, like "a swarm of digital hornets", "digital gold", "art", "revolution" and so on, it suggests that it isn't doing well as currency, because otherwise people wouldn't need to create new narratives of what Bitcoin is.
When a small percentage of people use strange and unrelated definitions to describe Bitcoin, it shows their mentality not what Bitcoin really is or how it's performing. For example from early days there has been some people who call bitcoin a "Ponzi scheme" but that is not a comment on Bitcoin but on their understanding of Bitcoin (or rather lack of understanding).
Bitcoin is performing very well against every other asset on a monthly chart.
Bitcoin is a digital currency. Bitcoin is a store of value. Bitcoin is the world's most secure transactional network. Bitcoin is public infrastructure. Bitcoin is at the core of the new and deflationary economic system. Bitcoin is code, and
Bitcoin is artArt is not a strange unrelated definition, but the broadest.
