The building is said to be European Central Bank. Based on my understanding (CMIIW), it wasn't really the ECB displayed the image but bitcoin folks there that just flashed it through the building. Sort of misleading but then they've got balls to do it.
It seems like sarcasm from a person who dislikes bitcoin. we don't have to be enthusiastic to respond, because it would be a boomerang on ourselves. If viral, this will be responded to soon by fiat enthusiasm to face bitcoin OG. This happens many times I see if we if engaged in politic, their target is dumping the price to buy more. I hope we are not provoked, and just relax, this is providing us with if bitcoin is already aligned with fiat.
