Nov 01, · Bitcoin claims that “It is the first decentralized peer-to-peer payment network that is powered by its users with no central authority or middlemen.” 1 That lack of central authority is the. Bitcoin has proved not to be a good portfolio diversifier given its increasing correlation with the stock market. Bitcoin has performed “roughly in line” with ethereum (ETH), undermining the argument that bitcoin has “distinct ‘digital. Dec 22, · Tapping into billionaire hedge fund manager Paul Tudor Jones who recently said, “A bet on Bitcoin is a bet on human ingenuity,” Keiser acknowledged Bitcoin as pro-humanity working for humans. He then defined the next phase of Bitcoin battle as “humans vs. AI.” Call For Evolution.

There is also proof of space, which involves providing an amount of memory or disk space as opposed to processing power plus many more. As time goes on, difficulty incrementally rises, which means that more processing power is needed to process every transaction on the Bitcoin blockchain.
These are huge increases that have a significant impact on the environment. The sheer amount of energy involved in processing transactions has grown dramatically, and will only continue to grow — a concern that calls into question the long-term scalability of the Bitcoin network. A study from Digiconomist in October showed that the power used to process a single Bitcoin transaction could power the average house for a whole week.
This kind of power consumption is clearly unsustainable from an environmental point of view. Initially, Bitcoin was being heralded as the next greatest payment system. One that had promise to revolutionize the way we sent money and disrupt all the major players in the space right now, from Western Union through to PayPal.
One of the flagship promises were the extremely low transaction fees and the speed at which you could send and receive funds. Things have changed a lot since then. Not only have the transaction fees exploded, but the average time it takes to confirm a transaction has been increasing too. In late , there were sustained periods where the median confirmation time for a Bitcoin transaction was over 20 minutes source.
If you compare that to the average time a block was confirmed with Litecoin — around 2. The question is, will that give the currency enough utility to stand the test of time?
Now, one huge caveat here is the rise of the Lightning Network which is already showing a lot of promise at reducing fees and increasing speed on the Bitcoin network. Similarly, the distribution of hashing power that is, processing power using within mining across the network is becoming even more centralized.
When large corporations, provide the majority of the hash power across the network, this actually gives those entities a disproportionate amount of power and control. As of March , BTC. Even if the intentions of the major players within Bitcoin mining are good and honest, this still puts a disproportionate amount of risk on the network. On a basic level, it exposes Bitcoin to regulatory changes within China. If the Chinese government were to shut down all Bitcoin mining operations in the country, that could have catastrophic consequences for the cryptocurrency.
A majority attack can take place on a blockchain when an attacker owns a large proportion of the network hashrate. The attack can be deployed in a number of different ways, but here are two examples of how it could theoretically work:. Selfish mining is when an attacker privately mines blocks at a faster rate than the rest of the network, and then forks the network to their version of the chain. This renders all the work carried out by the rest of the network useless and enables the attacker to take all the block rewards.
When a new block is discovered on the blockchain, miners use their computational power hashrate to find a solution to the complex mathematical problem posed to them via the proof of work consensus system. The network must remain on one continuous chain of blocks, so two chains cannot exist at the same time. Once the attacker has the solution, they begin solving the next block, and then the next block, and so on, attempting to get as far ahead as possible.
As soon as a miner eventually publishes their solution to the first block, the attacker publishes their hidden solution, forking the network in the process. As the network decides which miner solved the problem first, the attacker publishes the solution to the second block, making it the longest chain and ultimately the most legitimate. If this happens, the attacker can then go on to continue to publish solutions to the following blocks, gaining all of the mining rewards and removing the ability for anyone else to discover blocks.
They can do this if they own a majority share of the hashing power on the network, as they will be the one verifying the transaction they created. However, this is a very real threat to smaller networks such as smaller altcoins, and that has already happened.
Is there any substance to these claims? In order to secure access to their cryptocurrency, the owner generates two alphanumeric strings: a public key and a private key. A public key is visible to everyone and can be used to send and receive bitcoins. That being said, it is possible for an attacker to access an account without its private key. With altcoins still down so low, and potentially more danger ahead for the asset class as the SEC begins to stiffen regulations , whales could be waiting in the water, ready to liquidate their tokens as soon as they can.
Most altcoin investors who got in around , are still underwater and could be waiting to sell the moment they can, even if just to exchange for Bitcoin. It could be the primary factor behind why no alt season has returned, and the short-lived over the summer was kept to only DeFi tokens and other new alts.

My journey from a curious retail crypto investor to a serious Bitcoin advocate, trader, and technical analyst is an unusual one, but life-changing nonetheless and has become less about money and more about a long-overdue revolution. While a firm believer in the laws governing math and science, I am profoundly fascinated by the impact of astrology and astronomy including moon and solar cycles and planetary alignment and their ability to influence and potentially predict markets.
It hasn't yet clicked for me as to how to put anything to use, but I consider it my current rabbit hole I can't yet dig out of. My perspective of growing up alongside the internet, the dot com era, the Great Recession, and roots in video games collecting coins and rare items caused Bitcoin to immediately make sense to me. Through all of these lenses, I seek to produce content that is educational and entertaining, and I thank you sincerely for taking the time to read what I have to say.
