Yes and no. There are and always be both sides of the (Bit)coin: coin for use and "digital gold". Without it's every day use people will get to the point they can't redeem their "digital gold".
Also, I was also thinking that wealthy people will hide big amounts of money into cold storage and "hodl". But nowadays somebody is selling. Yes, it may be the rich guys that bought one year ago, but they sell instead of buying?! I mean, since the corrections we had this year, they should buying again.

So I think that there may be something wrong in this logic: it doesn't cover the whole truth (and yes, I know, there could be some market manipulation exactly because they're buying and they try to keep the price low while doing that). Still, something seems to be missing...
