I think there is indeed a lot of resentment. I guess only time will tell if it's warranted; most of my friends have no idea what they are (I did a fair bit of mining in 2013-14, but alas got on the bitcoin train way too late and small to make any significant money!), but everyone seems to have an opinion on them which is formed by the media's representation of them through large negative stories of drug money and contract killings. Whether they do actually change the landscape of global finance/money remains to be seen (I'm a fair bit less positive than I was a few years ago, despite the rise in price), but there's definitely a big PR battle for them to overcome with the general populace; most who know anything about them have only heard negative stories.
