Well, I never liked the term they called Bitcoin a 'virtual currency scheme'. Somehow I thought it had a bit of a negative connotation.
you mean it sounds like: "vapormoney scam" ?
agree whole heartedly here ... scheme naturally makes one think scheming or to scheme and while their use of the word is more akin to the definition that aligns with a system, the scheming term humans often get in the back of their mind when they see the word feels more like the definition akin to scam i.e. to scheme as opposed to a scheme
