What's the use case here?
It's marketing to a specific niche of tech bro, which is probably a large enough segment of Newegg's customers to justify it.
That's a long time to hold up the line at the grocery check out.

Again, I paid BTC for a laptop 9 years ago and it made sense for me then since it was mined BTC from 11 years ago.
In order to use BTC you need to obtain BTC and transaction fees kill any normal day to day use case.
This leaves BTC for less than legal uses where you do not care about fees.
So BTC itself might not qualify as a scam but as a mega enabler of scams and illegal activity.
EDIT: that $1.76 is just a on-chain fee for the network, most stores will charge you extra to use BTC since they do not care about BTC they want to cash out immediately so they use a 3rd party.
So unless you get paid in BTC you have very little reason to use BTC for payments.
It was exciting when I first looked at it and then I realized that this was actually not "democratizing" anything so much as ensuring a new class of folks would be able to create new centralized "everythings" in a new environment outside of the current system - without the benefit of the years of testing, regulation, and (sure) cruft that our current systems have because they're subject to political forces (which is actually a feature).
Maybe starting the wild west over again is a good thing? My money's on "not really" at the moment.
