Your point assumes the demand is rising, but it isn't... The demand has existed for a long time, recently it has just moved from inside exchanges to OTC.
Like I have said long time ago... The demand is either flow towards other cryptocurrencies or towards cashing out... The demand is never towards HODLing even if some account holders like to HODL some of their coins.
