“But Bitcoin has scammers!”
“Bitcoin has scammers; therefore, Bitcoin itself is a scam”.
This is a really bad argument.
Imagine if someone used this argument in any other context, such as the following example: “All private enterprise needs to go away because some people are scammers and don’t provide anything of value.” Or, imagine if I said, “There are gold scammers, therefore gold itself is a scam.” Plug in any asset and you get the same bogus reasoning! Garbage reasoning goes in, garbage comes out.
