The truth be told, not everything has to be on the blockchain, and if we take this into consideration and remove greed, we will certainly have few projects being launched through ICOs. And people could use the blockchain without tokenizing any asset on it, blockchain has some useful real life application such as monitoring a supply chain, securing data or records and of such applications
I agree here. There are many compelling applications of bockchain technology especially in record/data keeping as it is immutable. It can be use for election too and in any industry. Blockchain can speed up transaction,and help a lot in remittances and financial system.
Of course we need this technology for our comfortable future. Due to this technology everything will be digital like your camera and mobile. We will feel more easiness in life. But to understand this technology we need long time because it is very complicated and even the governments do researches to know blockchain technology. This will be a new era and I am waiting for this technology anxiously.
