What role, and why is it uniquely well suited for that role?
Speaking for myself, back in 2013, I was excited by what I saw as its potential for micropayments on the internet. That is (and was) clearly wrong - it can't do the transaction volume, is too hard to safely acquire and use for most people, and is too volatile.
Its current role is "hype-y speculative security". I don't see a significant and long-lasting need for such a thing, or how bitcoin is uniquely qualified to be that thing.
> I would advise anyone to only invest in what they know.
What is it to "know" a thing? Put another way, what exactly makes it such that you "know" bitcoin? Put another way, what useful information is there to know about it? I understand the details of the whitepaper and the block-chain concept at a technical level, because I find them innovative and fascinating, but I think any translation of that technical with knowledge of its value as a security is illusory.
I'm honestly curious about this: I've gone from very bullish to very bearish over the last 5 years or so, while I've watched the population at large take an opposite course from indifferent and unaware to very bullish, and I'd really like to understand what I'm missing.
