Thanks to the author for the article, it is very systematic. The development of Bitcoin can also be said to be the biggest obstacle facing the development of decentralization is the relatively high upward pressure. Sovereign states in the real world will continue to exist for a long time. Bitcoin now has a little 'utopian' flavor, but decentralization still has many advantages.

• The decentralized system is more resistant to risks. This is compared to a centralized system. Because there is no decisive central node, you cannot destroy the entire system by destroying the central node.
• Users in a decentralized system are more equal. The centralized system will use the media to induce everyone, or specify policies for everyone to follow. In a decentralized system, everyone can speak. And they will all have equal opportunities to express their opinions.
• The decentralized system consciousness is bottom-up control, which determines that most nodes in the decentralized system are very satisfied with the system. The decentralized system eliminates the corruption, greed and brain development of the central node. Negative factors such as water (President Joker) cause serious damage to the entire system.
• The decentralized system has unlimited possibilities. Just like biological evolution, a diverse ecology has been developed. Over time, many altcoins have broadened the application scenarios of Bitcoin and will develop a perfect decentralized blockchain financial DAPP.

To examine each issue with a dialectical perspective, the shortcomings of decentralization also exist.

• Due to the huge number of nodes, a decentralized system tends to become a bloated organization, so the efficiency is much lower (compared to a centralized system), which means that the cost of communication is relatively high.
• The decentralized system is uncontrollable and unpredictable. When a certain consensus has a huge divergence, it will form a fork. This does exist and it is difficult to avoid.

Today's world is a highly centralized management model. The state is in the hands of a few groups and the company is in the hands of the CEO. But as a great experiment, decentralized Bitcoin will become an opinion leader leading change.
