If there is too much public opinion about a thing, then most of this thing has a demon.
If everyone wants to make money through the blockchain, it means that the chances of making money are no longer great. The redistribution of wealth has never been to everyone's share. Calm down and think carefully. The virtual currency that is now being favored by the public is represented by Bitcoin. If there is no payment function, what meaning does it have in addition to speculation? Why is the use of blockchain technology all talked about is not focused on the application of virtual currency in retail payment?
Bitcoin is mostly seen as an asset, as an investment, as an store of value or even compared as "gold standard" by some people. This is why so many peoople even enter the arena of bitcoin as it price makes it to the news and nothing more. Bitcoin has still long way to go to become the best and widly used exchange medium like national currencies are today. However there are soem places where you can spend your bitcoins.
Redistribution of welth has never been to everyones share : you have this with fiat as well. Those who work hard win at end theres nothing much else to it. You can't expect somebody to give you free money for you to live good.
Blockchain is a new thing, actually not so new, but why it matters? It matters because you can have decentralized system where everything is tracked. So currency such as bitcoin is only one application and one purpose of blockchain. COmpanies for instance are looking to implement blockchain, at least some of them, to have some smart contracts going between other companeis they are woring with. Now every company can connect to same blockchain (this is private blcokcahin since you can't run a node and influence on the way how the protocol is issued as an indivudual) without the need for them to have different databses and then try to to fill the gaps. Here evrything is transperent and everything is tracket with every participant having the copy of this ledger and thus enabling you to have whole new applications and use cases. Cryptocurrencies are not talked about much since it's future is uncertain and it is mostly use for speculors to try and flip the buck - however this may channge. If in future we have some stable cryptocurrency and goverments give it green light well we could look at it being talked more.
