I recently watched the movie Goosebumps 2 with my kids and Bitcoin was once again mentioned briefly in this movie. The one boy mentioned Bitcoin and the other boy called it Nerd money.
So it got me thinking, why would people label Bitcoin as Nerd money, when people use electronic payment options like PayPal every day? What feature about Bitcoin gives people this impression about Bitcoin?
The first thing that comes to mind is the technical IT knowledge that people need to understand the concept about this technology and also it's origin amongst very highly skilled programmers and developers in the IT industry.
I am definitely not a nerd, but I am more than willing to carry that label, if it means that Bitcoin should be part of my skill and knowledge set in this world.

Bitcoin Nerds will rule this world!
I also have watched that movie last year and have seen some people on the internet refer cryptocurrency (not only Bitcoin) as nerd money. I think some people refer Bitcoin as a "Nerd Money" because it was developed by a computer programmer and they think that the technology behind this (blockchain) and terms that are being used is hard to understand that only computer nerds can only understand and maybe because it is a currency/asset that is in form of digital. But people will surely stop saying that cryptocurrency is a nerd money when it started to be adopted by more people and businesses.
