This is what I tried doing on a Saturday night. But nobody really knew what bitcoin was. I was the only one paying with bitcoin.
As people came to the bar or sat next to me, I made small talk and asked if they knew much about crypto, but most didn't even know they were in a "bitcoin bar." The bartender told me he only had a wallet because people wanted to tip him (the bitcoin payment method didn't give the option of a tip). When I asked him "what percentage of people pay in bitcoin" he got weaselly until admitting nobody really did except on thursdays, which were when most of the bitcoin enthusiast types came in.
There was a gathering of people in the back room and I asked someone if that was a meetup, but I was told it was a birthday party.
A man walked through playing bagpipes because it was "Robert Burns Night" which pissed off some of the girls with more sensitive ears who asked me and others to tell him to stop. But the bartender served free shortbread for the occasion.
Most people in the building were young professional corpo/finance types or had the new-right, serif-font david protein bar aesthetic.
I told some of them they were in a bitcoin bar, pointed to the price on the wall, and they said they didn't trust it or had a small position. Most said it was too volatile. A person said he was pissed for selling all his at $80k since he would have made more selling at $100k. Someone recommended I invest in VOO instead.
So next time I'm in new york I'll try to make it on a thursday :)
