Good question !
I was in this kind of position a year or two back when I began my crypto journey. The key thing is that at that point, most people (especially ordinary people rather than IT specialists) only have very limited knowledge, and most of that is snippets (often inaccurate or biased) from the mainstream press. People don't know about use cases, tokenomics or anything like that.
So I feel the answer will always be along the lines of "Bitcoin plus X". The X will depend on what takes their interest, but it'll probably be something we think of as relatively mainstream - one of the top 20 or 50 by marketcap. I'd guess either a really established memecoin like Doge or SHIB, or whatever Elon Musk decides to use on Twitter are the top possibilities, with Ethereum another good candidate.
Our job is to tell people about HIVE and get it into their minds as one of the crypto's they first think of if they go from slightly interested to actually getting involved !
