Calling Ethereum a house of cards is terribly hyperbolic but to clarify, here is what Ethereum has going for it.
These are some of the companies, banks and countries interested in the technology. J.P. Morgan Credit Suisse CME Group British Petroleum UBS ING Microsoft Thompson Reuters
Countries: Singapore Russia China
The United Nations even sent aid to 10,000 Syrian Refugees Using Ethereum Blockchain. http://www.coindesk.com/united-nations-sends-aid-to-10000-sy...
...And I am not "taking a piss" and neither are all of the above Ethereum businesses, countries and banks.
My best estimate is that the ICO market as a whole will have to be at least 3-4 times more successful than VCs if the house of cards is to stay standing. We're talking about a process that has to churn out unicorns to stay afloat.
Do you think smart contracts really make every business that uses them 3 to 4 times more valuable?

I honestly can't tell if you're taking the piss.
