... basically NOT TRUE and reminds me the "good" old days of internet bubble 15 years ago when dot.coms were the only assets leading us to a new better world of prosperity 
Market cap of dot.com bubble was 500x higher than we are now with crypto.
On finance market are so big $$$ comparing to markets crypto is 200x-2000 smaller than some stock and commodity exchange.
When crypto will go to 40% market of gold i would say u need worry but crypto need rise 70x-80x to get there.
While crypto is much more useful than gold.
Today BS about crypto bubble is far from reality how much money people can drop here haha...
