The intrinsic value of bitcoin, yes that's a good one
another one we are playing with is how they blame it to waste electricity for nothing
(when visa and mastercard waste 1000s times more in infrastructure and others for much worse service)
These are 'arguments' that are used by people who have nothing left to argue with, it's a bit like arguing with religious people because in the end they've already decided what they believe and will just say whatever the hell they like, I know you guys are clearly way more patient than I am but the people who make these comments are never going to watch your video ( precisely because they know it will prove them wrong ) and they're never going to listen to the arguments against them, simply because they don't want to.
p.s. If you're really that determined you could also do a video on stupid shit like "Is Bitcoin like the tulip mania?"
We kinda covered that in the Ponzi one
About the rest, yes I agree, most would ignore it but with the time some of them will slowly convert. Change needs to be digested very slow by most people.
Once they are ready, those videos will be there for anyone to watch.
