Thinking about the blockchain: The terrible thing is not the blockchain but the human mind!

The blockchain is a popular keyword on the Internet recently. Under the banner of “innovation”, blockchain projects have sprung up.
Looking at the wave of funds flowing into various blockchain projects, either real or fake, we can't help but ask, is this market a bubble?
In the past few days, my roommate has entered a bitcoin trading group. He is usually a student who only knows how to play games. Now he always talks about blockchain, ICO and cryptocurrency! Since then, I have been inspired by his strong curiosity and decided to study it. What is bitcoin, blockchain and ICO? How to make money?
After a period of understanding, I got the following view: If the blockchain is used correctly, the world will become more fair and just, and many things will become safe and transparent.
People who rely on it to make money but lose money refer to the block-chain and will insult! So there is an old saying: The terrible thing is not the blockchain, but the human mind.
