As for dinners, my dinner friends won't let me talk about bitcoin for more than 30 seconds each night. And they are as surprised as you are that I be wasting so much time with this [ expletive deleted by self-censorship subroutine ].
I see. Your dinner friends understand Bitcoin. You should try to learn from them.
If you don't know yet, "bitcoin" is a negative word in the real world, do not talk about "bitcoin" in family/friends gathering, you will be isolated and treated as "online criminals and ponzi sellers" for this foolish behavior.
