I’ve been saying that for years ! 
But it keeps on - and on -and on !
Clearly it’s viewed as a “Safe” commodity - like Gold and Silver - just at the moment but with the added temptation of spectacular rises being hyped.
The thing is tho’ with “interest rates” pretty certain to stay at zero - for the foreseeable future and the dollar plus all other currencies being pumped up to make believe levels,
AND Stock markets seeming to pretend that “Times are good” - what on earth are youngsters who can’t access “Real-estate” supposed to do with their money ?
Keep it in some bank ? and await Inflation to decimate it or centimate it ?
Maybe the kids are already expecting Student Debt to be written off at Our expense and instead of repaying it pumping the money into Cryptos ?
Dunno - We’ll have to wait for those who have been dancing around the fires for teh last 4 years chanting “Burn the Witch” - to explain to us how and why any form of Economic survival for the US as a whole and individuals within it in particular is even possible !
