@builderofcastles you are undoubtedly correct in correlating the prefix smart with spy. Spy meters, spy phones, spy cars... that was genius. I do however agree with @tommycordero on the term cryptocurrency. Crypto sounds intimidating to the average person. The gentleman checking me out at the store said he was drawing on his 401K and hoarding gold and silver. I offered a suggestion on diversifying with cryptocurrency and I immediately thought of the "dark web" and "silk road". He's also older than Jesus.
