In a decentralized digital asset no government can interferes with the system thus making the system uncontrollable by any authorities but it can only be regulated or outrightly banned by the government.
I prefers a decentralized form of digital assets to a centralized system where the authorities will take control of the asset there is likelihood of manipulation by unfaithful and corruptible powers behind  those system

Completely agree with you, mate. Decentralization is the way to go since it gives the power back to the people instead of corporations, governments, or other centralized entities. The level of success that Bitcoin has experienced today, is due to its decentralized nature. However, if it becomes centralized then investors might flee into another cryptocurrency which is decentralized as Bitcoin becomes extremely vulnerable to 51% attacks and external manipulations.

Eventually, I believe that most centralized systems might fail in the future, as decentralized systems would provide unparalleled security, reliability and other benefits which are too hard to ignore in the mainstream world. Ripple or should I say XRP, is centralized and it could fail anytime, considering that it relies on banks and governments to succeed. The moment its internal company decides to freeze assets on the XRP ledger, or governments decide to take over the network, then the whole system will collapse.

On the other hand, that's not the case with decentralized cryptos like Bitcoin and Ethereum, where nodes are widely distributed across the world, and there's a lot of hashrate backing them. For governments or other entities to succeed in destroying such decentralized systems, they would need to spend a lot of money to perform a 51% attack, block BTC nodes, among others to disrupt the network. However, as the number of nodes and miners grow on the network, the cryptocurrency becomes stronger and impenetrable against external attacks. Therefore, decentralized cryptos like Bitcoin and Ethereum will win as they become unstoppable over time. Just my opinion

How to control the miners in other coins that are also too influential? In decentralization the criminals are free so this is also a problem. Centralization is much worse though as the top as always will rule and control everything according to their means.

A decentralized system is a very good thing, I think so.  It is a more modern approach to the development of any sphere of our existence. When there are several control centers, it is much better because Monopoly is the last century.

there are now so many developing decentralization, and in my opinion the best is centralization like bitcoin. if centralization all get connected easily.

the success recorded by the blockchain technology today in the globe is as a result of the features that was embeded in the design and one of which is the decentralization. It makes the technology void of any kind of influence bot from the government and other agencies. if it is removed then it is no longer what it was designed for.

if you think that way, Crypto certainly will not get worse even though this is not properly decentralized, and there may be some phases in which crypto has a real impact on the world, because the technology carried there is so obvious and probably there will be no comparison to the technology blockchan have

Centralization of bitcoin negates the purpose it was established or created for, with its decentralized feature there is no bank or government that can regulates or manipulates it because of the trustfulness of the technology behind it (blockchain) I fully supports decentralization of it.

Decentralization is one of the pillars of the constitution of bitcoin and can not be reversed, as it would be its end. 
Crypto and decentralization are synonymous.

YOU have a great point I'm not favor bitcoin or virtual currency become centralized currency and control by one group or government, but if that idea are the way for for cryptocurrency become legal and the worldwide why not but need to learn it well to avoid manipulation of cryptocurrency value in the world market.
