Difference Between Centralized and Decentralized Blockchains

There are two basic types of blockchains:

 (1)Centralized Blockchains
 (2)Decentralized Blockchains. 

The most commonare decentralized,but all blockchains are distributed. In the centralized blockchain the distribution is between the nodes of the owner and partners/investors.The main advantage of decentralized blockchains is that it is open source and anyone can join and contribute. Currently approximately 50,000 programmers all over the world are contributing to decentralized blockchains. And they share their knowledge with each other. They are very diverse and distribution is much easier. Regarding centralized blockchains, that is not the case, because the mining is done by the owner of the blockchain and distribution is confined to a much smaller group of people. Centralized blockchains according to some critics are just an upgrade of the centralized banking system more than the progression of the blockchain,which could be considered to be partially true, but not entirely. Both systems have their good sides and their bad sides.It is a huge world, a huge market, and everyone can think for themselves.
What Is The Overall Advantage of The Centralized System? 
The processing or hash power of the network does not need to increase because it can remain constant and the number of transactions can remain constant. But if they wanted to increase the processing or hash power, the number of transactions can also increase with it. So centralized systems can increase the number of transaction far easier and faster than any decentralized system. In the long term, this is far more significant than most people realize.
Transaction Speed the Main Advantage of Centralized Systems
To put this into perspective, for example, OneCoin can support 100,000 transactions per second, VISA 54,000, PayPal 450, Ethereum 25, Bitcoin 5. So if we look at global use, the decentralized systems chances of increasing their transaction speed is very weak. Centralized systems can increase their transaction speed in a matter of days by just increasing their processing power. That is the main advantage of centralized blockchain systems.
Bitcoin Fees Are Increasing With regard to fees, Bitcoin is increasing, and others are following suit. Very few people anticipated that. And the fees will only continue to increase. So it is  not a cheap system to use.
Exchange Monopoly Cartels Hate OneCoin
Unfortunately when people are first introduced to OneCoin, they search the Internet: What is Bitcoin? What is OneCoin? They go through all the hater stuff and they catch themselves on the price. OneCoin is $25 and Bitcoin is $8,000, and nobody asks why. Bitcoin has a monopoly. If you go to the exchange, you must use Bitcoin to buy any other coin, and this is the monopoly cartel (organized agreement to maintain prices at a high level and restrict competition) created by the exchanges.
There are 4 basic steps:
1. You deposit your money on the exchange
2. You buy Bitcoin
3. You exchange Bitcoin for another Digital Currency
4. Then you withdraw those coins into your eWallet
There are 4 fees to be paid and this is a global agreement for every exchange. They all make a lot of money on these exchanges and they do not intend to change that. Any Digital Currency that bypasses this entire global exchange system is their competition and their enemy, and they will do anything and everything to destroy this competition.
Big Advantage of Centralized System.
Regarding technical aspects, and if we look at the long term solution, the centralized system has a big advantage.Why? Consider this old Bitcoin commercial from 2013, and it sends a very good message. Western Union send $50 for $5 fee for pickup in the US. Bitcoin send any amount for only $.01 for pickup anywhere in the world. And that was the initial advantage.
Big Disadvantage of Decentralized System
The entire problem of the decentralized systems is, as people join the mining pool, the processing or hash power of the network is increasing, but the speed or number of transactions per second is staying the same. The mining requires very expensive computer processing power and increasing cost of electricity, so over time the cost of each transaction is becoming more and more expensive. And what they should do is, as the power increases, the speed should also increase, but that is not happening. This increasing cost per transaction is due to the disparity between the increasing power cost and static processing speed. And this is what the normal ordinary Bitcoin enthusiast does not understand. I have had a lot of arguments with them, but they are mostly fascinated by technology, and not anything else. They do not care about usability, they are not interested in the value, they just recognize the systems that are copy and paste systems the same or similar to Bitcoin. And everything else to them is not valid.
The main advantage is diversity and innovation because there are now blockchain systems for almost everything public and private. For example in a recent test, Sweden’s land registry process was reduced from 4 months to only 5 days using blockchain technology. That is how much faster the system works on the blockchain.
Cons of Decentralized Blockchain Systems.
The disadvantages.
The main disadvantage is high risk of abuse, anonymity, and the problem with network consensus. When the network had to increase the blockchain size for Bitcoin, to allow more transactions, their network started almost a civil war. Now we have Bitcoin, BitcoinCash and BitcoinGold; and everybody against everybody. The price doesn’t show it, but the system is in turmoil.
Process of Decentralized Blockchain Systems.
They are usually static and not susceptible to change, usually high competition between them, and while network marketing business model can be an advantage, it can also be a disadvantage. What is the greatest strength of OneCoin? OneLife network marketing. What is the greatest weakness of OneCoin? OneLife network marketing. Because we had leaders who were not good and did bad things and they contributed to the bad reputation, and we had good leaders who made a good reputation. But the press and the general
public always focus on the bad things. So you can do 20 good things and 1 bad thing, and the press always reports on the 1 bad thing, and they will never mention the 20 good things.
