We all know something, no one knows nothing. We in crypto were smart enough to know the legacy systems suck - which is why Bitcoin is up 30,000%
Crypto is NOT too high - all of Crypto is less than the total value of one man (Bill Gates). Crypto still has a long ways to go. Wait till all of the Stock Markets are moved to Bitcoin or Ethereum using just Exposure. Just like we use to browse the internet over phone lines, and now we make phone calls on the internet. You can even spend USD or EUR or CNY without ever leaving the Blockchain. Wait till there is more FIAT being used within Blockchain than in the pockets of people.
All the big corporations are Intermediaries of the people. Corporations do not make anything - people do. Intermediaries, Fees, Taxes, Agents, Brokers, Rent seekers, Registration, Licensing, Permits, and a million more, take all the excess money. With Smart Contracts, we can one day delete those middleman industries, which suck the life out of the productive industries that you are referring to. Just wait till the fall of FIAT.
The Crypto world is severely under valued. It's not even bigger than one man (Bill Gates) when it will be bigger than Wall Street. I'd love to hear how you think Wall Street can blow this up with the precision of a Quant Surgeon. These guys are not that smart. They win by force, but the blockchain cannot be threatened, it doesn't have a Fight or Flight Nervous system that worries about it's very existence. You can't point a gun at the blockchain and even if you did, it would not be scared.
IMHO
