Like you said, this will attract publicity for the company. As for bank notes, obviously for the people who have been immersed into crypto space this is not a good way to go. However, there are a lot of people who want to get into crypto, but it still seems for them like rocket science.
Let's admit it. Many people don't feel comfortable about using wallets and exchanges. And don't let me start with old-fashioned fellows who cannot stand fractions (0.02 BTC). They are used to integer figures.
Anyway, this company knows there are still some gaps for massive adoption and they're tapping on them, for their benefit of course.
Yeap, that's exactly what I concluded as well, nicely said!
