Depends on how far it is explained. Some people can handle longer, more intricate explanations better than others. The "others" here I would surmise would in general be more likely to regard Bitcoin as a scam.
As soon as I heard "decentralized", "limited supply", and that it was all controlled by cryptography across a distributed database on a P2P network, I understood it to be something that I need to devote a large part of my life to.
But when I explained it this way to some 60-year old (more or less) average people, they couldn't see how it could possibly be anything other than a scam. Granted, one of those people continues to think the entire Internet is a scam...
but these days credible news sources are calling a scam,
do it man google "bitcoin"
you'll find a lot of bad news if you do any digging
this could easily fool even reasonably smart people into thinking its a scam or not worth while
I think the threshold for "reasonably smart" is telescoping and increasing at a geometric rate, somewhat in proportion to the expansion of technology and the concept of intelligence building on intelligence. A simple google search won't give as much accurate information as it once did. New and innovative and exciting things and technologies will begin to appear faster than the general human populace can process it through their meat brains. I can envision a future where the Web as we know it now becomes completely watered down, much like basic cable television nowadays, and the only access to real useful information will be via dark nets, via things such as (or based on) Tor, and this basic action of seeking out useful information might also be seriously regarded as terrorism or something like it.
If you have access to databases such as LexisNexis and ProQuest, you can find much more positive (and scholarly) information on Bitcoin.
