Do you think Bitcoin is decentralized? I guess 95% of you will say YES but after this little analysis, I think that number will be lower. First of all, I am not hating on Bitcoin, I love BTC because without BTC, market would collapse. However, I was just curious whether Bitcoin is really decentralized? As I said, most of you will say ” Yeah, it is “, I would say so too but after giving it a few hours of thinking I am not sure if it is decentralized or not.

Why?

To understand this whole review, first you have to know what mining means. Mining is a process where we use special algorithms to find solution on how to confirm transaction. Without mining, transaction won’t be confirmed, price will slump and all bad stuffs would come. So, without mining, there would be no Bitcoin.

bitcoin decentralized

Let’s Suppose If there are 1 million miners, Bitcoin will be decentralized because none of them is able to control Bitcoin.  And here is the biggest problem, there are a lot of miners but there are also mining pools. They are huge. For example, AntPool and BTC.com are the biggest at the moment with percentage of 16.9% and 15% respectively and total 31.9%. So only 2 mining pools are almost one third or all mining power. 3rd one is BTC.top with 13.3%, 4th is SlushPool with 12.4%. These 4 pools have total mining % of 57.6 (Dated: 11 December 2017). So, they are mining more Bitcoins than all others together.

Still think that BTC is decentralized?

What would happen if they decide to cooperate and decide to stop mining or something like that? Bitcoin will encounter a HUGE price inflation. These problems wouldn’t be unresolvable but enough to make big correction that would last for few months if not years. What would happen if they decide to make their own version of BTC and stop supporting current BTC? As we have seen Power of Forked Bitcoin Cash and some glimpse recently when it touched ATH of $1758 back in November.

This is a big problem for BTC. Main idea was to create decentralized money but, for me, result is not same as the idea. They are able to manipulate and make huge money and grow every single day.

Want create site? Find Free WordPress Themes and plugins.

According to Fintech Finance reports, Smart Package, which is an application of US trade giant Walmart, has been released by the US Patent and Trademark Office (USPTO) on 1st March. Smart Package patents employ a tool, based on blockchain to track down the location, environmental conditions, package contents, and other details. The main purpose of such blockchain applications is to be used in the latest technologies like unmanned drones etc.

blockchain applications

Such blockchain applications help in recording the main addresses like; seller private key address, a buyer private key address and a courier private key address. According to this application, the current tracking instruments don’t offer such coveted functionality yet. Fintech Finance also reported that Smart Package application was first filed by Walmart in August 2017. This application isn’t the first one, in which Walmart has utilized Blockchain technology because, Walmart merged with IBM, back in 2016.

UPS, which is a US shipping company joined BiTA in November 2017 because, blockchain technology is quite popular among delivery and shipping companies. Publication of a non-conditional patent application occurred almost 18 months before its initial precedence date in the US. Once it’s published, USPTO can use a patent application to reject the third-party patent applications for the correlated technology.

John MacAfee Bets His Manhood – Says Bitcoin to Hit $500k In 3 Years

Want create site? Find Free WordPress Themes and plugins.

19 July 2017, A passionate digital currency backer says that Bitcoin is going to hit $500,000 during the next three years.

According to him, Bitcoin’s potential is not a joke, and that he is ready to take any bet to the contrary.

People were quick to respond:

One might think that McAfee is on the extreme end, but he is not the only one manifesting this much optimism for Bitcoin. Tom Lee – one of Wall Street’s biggest equity bears – also believes that Bitcoin is the new gold with a potential worth of $55,000 by 2022.

“One of the drivers is crypto-currencies are cannibalizing demand for gold GCQ7, -0.20%”, Lee wrote in a report. “Based on our model, we estimate that Bitcoin’s value per unit could be $20,000 to $55,000 by 2022 — hence, investors need to identify strategies to leverage this potential rise in crypto-currencies.”

That’s a major jump from $2530. Lee considers Bitcoin as a Gold, and the reason for this is the ever-increasing value and high demand of Bitcoin. Lee added, “Bitcoin supply will grow even slower than gold.” And, “Hence, the scarcity of Bitcoin is becoming increasingly attractive relative to Gold.” Lee also wrote, “This is a game changer, enhancing the legitimacy of the currency and likely accelerating the substitution for gold.”

Today’s value of Bitcoin is $2303.28, which reached $3018 on June 11, 2017. However, the drop is just being touted as temporary, and Bitcoin is expected to pick up the pace again in the coming days.

Bitcoin Averted a Split – What’s Next?

Want create site? Find Free WordPress Themes and plugins.

The Bitcoin development community is embracing a software upgrade which is known as SegWit. The purpose of SegWit is to increase the transaction capacity of the network and to avoid a split which possible in the cryptocurrency. As Bitcoin averted a split and here is what some proponents have to say about “What’s next for Bitcoin”.

Adam White:

The head of Digital currency exchange ‘GDAX’, Adam White said, we are going to experience a better utility of the network. People can use Bitcoin as a source to transfer money more easily, more cheaply, and more quickly. It’ll attract the new users to the network.

There’ll possibly open blockchains like Bitcoin as we’re going forward, and that will be slow or conservative progression. But there’ll be other blockchains as Ethereum which may move much rapidly and it’ll introduce a larger platform for developers to lead it at the top. According to Adam White, both things will balance each other, not compete.

Elizbeth Stark:

According to the head of startup Lightning Labs, Bitcoin does not have Turning-Complete language as Ethereum, but there are some new amazing factors which will enable to do so when SegWit will implement. She gave few examples as:

  • Small transaction as less than 1 cent, which may replace “ad networks”.
  • Instant-transaction confirmation in milliseconds.
  • Bitcoin can get a lot of its own ICOs.

Matthew Werner:

The head of payments engineering at Coinbase describes that it is a beneficial step for Bitcoin. There were a lot of queries about a Split but reaching a consensus for how to scale the Bitcoin further is obviously a huge step. Allowing things like Lighting Network and activating SegWit will be a great thing. By expanding the block size, we’ll be able to increase the number of users on a network. The element BIP91 came through and it’s a good signal because everyone wants to grow this network further.
