I mean that I consider cryptocurrency scene to be net social negative (a nasty breed of fraud, gambling and MLM) and cryptocurrencies themselves a technology that's an environmental disaster and which should have never left the research stage. As for Uber, their only innovation so far was showing the sheer scale at which you can make an inherently unsustainable business built on anticompetitive subsidizing and illegal behaviour without people noticing.
> I mean that I consider cryptocurrency scene to be net social negative
This sounds like nonsense. Cryptocurrencies allow people to perform secure financial transactions without relying on central banking systems, and to use the blockchain for things like decentralized time-stamping, automated escrow, prediction markets, online voting, and other services. There’s a huge amount of social value to these innovations.

What specifically are you referring to?
> should have never left the research stage
I’m glad it did. In addition to their utility as decentralized mediums of exchange, they have inspired a lot of research in the fields of game theory and cryptography, including work on voting protocols, mechanism design, and secure multiparty computation. I think the world is much better off with this newfound knowledge, though you seem to think otherwise.
> As for Uber, their only innovation so far
Their innovation was revolutionizing ridesharing and ride-hailing. In 2015, and in the United States alone, they created $6.8 billion of consumer surplus [1], a surplus which has only increased since then. Over 95 million people use it on a monthly basis [2], with 14 million trips completed each day [3]. It is popular with the public, especially the young [4]. There is huge demand for services like Uber and Lyft to become more widely available. See for example [5].
You clearly have an axe to grind and it’s clouding your ability to evaluate things objectively.
