What does a scam mean? That it doesn’t have value? That it only has value for a select few scammers?

Crypto as a way to avoid taxes, buy goods on the black market, and as an alternative to a shaky local fiat currency are all great examples of crypto’s value.

Also, there’s also the investment angle. It (hopefully) operates as an uncorrelated store of value much like gold or other precious metals.

I think it would be very hard to argue that BTC and ETH are scams, that is, created for the purpose of the scammer stealing from the “scammee.”
