Hello everyone.

When I see there are too many ICO and shitcoins on novaexchange. I keep asking myself: do we really need blockchain technology?

In case of Bitcoin. Of course, I agree.
What about ETH? I agree too.

But, have a look at the others on the market. I don't even know why should people use their service. There is no real use in real life.

An ad management system on blockchain? - We already had Google Ads & Facebook Ads.
A social network on blockchain? (steem) - Do we? I don't see anything but a centralized forum hosted on a random hosting using its currency to pay for the writers.

There are too many projects  that we don't really need it on blockchain.

Sometimes, I think there is a black swan (Blockchain is useless in real life) lurking around.
