It's very early days, as of yet.
In most recent memory, just look at how long it took for the Internet to go from "something esoteric for a handful and nerds and academics" to being fully mainstream. Even when we'd had the web for ten years, it was still a relatively select group (relatively speaking) using it.Or look at something like PayPal (representing non-bank money transfers)... it was years before people stopped thinking they'd get ripped off because no bank was involved.
Bitcoin-- or just "cryptocurrencies"-- are going to have a hard time moving outside of specialty niche territory until people want to USE them to pay for things. Right now, everyone is getting into cryptos because "oooh, they might go up in value!", not because they want to buy cars, shoes or coffee.And I think the cryptos-as-money user is a different person than the cryptos-as-investment user, in many cases.
I think "digital gold" is a good analogy... it'll become well known to the world, but remain somewhat niche-ish. If we reach $5 trillion market cap in 5-10 years, that'll be pretty good going.
