Every time someone gives conspiracy theorists new contrary evidence they just say "You don't understand, that just shows just how big the conspiracy really is!"

Similarly, on r/buttcoin, when people give evidence on the value of bitcoin technology (like Yellen's latest comments http://www.coindesk.com/fed-yellen-blockchain-important-tech/) this sub just says "You don't understand, that just shows how much bigger the hype bubble is than anyone expected!"
