I bet your in-law doesn't know your moniker on this forum (obviously he isn't a registered member), otherwise that might cause you your in-law ship with him for using such strong word on him. You see, life has different shades to it. That someone differs with us on issues doesn't make him a less intelligent person. But more importantly is the fact that people like to chase price. For these people it shows that patronage determines the usefulness of a thing (this is not totally correct) This was what happened with Bitcoin in 2017. People like your brother in-law helped boost the demand and sent price to the moon. We need more of his ilks to ride us to another FOMO in 2019. May be we achieve a fresh ATH.
