I wonder / I'm sure there's crypto counterfeiters out there at the moment, but like, advanced scams; back when Bitcoin first became a thing you could get BTC medallions made that contained your crypto wallet private key (not sure if it was embossed, digital, or on a piece of paper inside); a scam I can think of is to sell those as a physical way to sell BTC, then have all of them refer to the same address. Or attach a website to it with fake wallet amounts and values - that works pretty well in Eve Online's most famous / common scam, where a user is linked to a website showing the scammer's transaction history "proving" that they sent money to the victim and lots of others.
