The father of Bitcoin was able to not only code an exceptionally well built system, but also found clever ways to ensure his work was validated and not misunderstood for some sort of a scheme by others. For example, Nakamoto left a message inside this first manually altered code. When the first block of Bitcoin was mined, it read ‘The Times 03/Jan/2009 Chancellor on brink of second bailout for banks.’ This quote is the headline for The Times newspaper which was published on January 3rd, 2009. The clever use of this simple message is overlooked by many, and it dictates that the first block was mined no earlier than January 3rd, 2009. This is extremely important because the whole Bitcoin system is designed to run and validate itself from the previously mined blocks, so giving a valid timestamp which can be authenticated by a simple headline title to the first block was genius. Afterwards, all blocks used the previous block for reference.
Simply put, whenever a user sends a certain amount of Bitcoins to another user, a third user verifies this transaction and publicly notates it in a ledger which is accessible by anyone. This ledger is called the “blockchain.” As time goes on, more and more users see the transaction in the blockchain and are able to verify it again. The more times each transaction is verified, the more secured it becomes.
The response from OP and all comments here in this thread seem to attack the author instead of attacking his arguments. Even OP long response revolves around ultrage someone could ever write something bad about crypto and question the author knowledge or capability. Guess what? Even someone with less knowledge than you can have valid arguments. Attacking the person instead of the arguments only make you sound dumb and just impedes a conversation we should be having.
Earlier this year, the Dogecoin community raised funds for the Jamaican bobsled team to attend the 2014 Winter Olympics when they could not afford to go. The community also raised 67.8 million coins (about $55,000) to sponsor NASCAR driver Josh Wise, who drove the Doge-themed car in races.
Nakamoto’s software would allow people to send money directly to each other, without an intermediary, and no outside party could create more bitcoins. Central banks and governments played no role. If Nakamoto ran the world, he would have just fired Ben Bernanke, closed the European Central Bank, and shut down Western Union. “Everything is based on crypto proof instead of trust,” Nakamoto wrote in his 2009 essay.

Specific examples and statements aside, Gates’ overarching concern appears to be that governments will not be able to track and regulate the use of cryptocurrencies like they can with minted currencies. That is, of course, part of the appeal for many crypto advocates, but the concern from critics is not completely unfounded. As with all new disruptive technologies, those participating in this movement will have to tread carefully.
In cryptocurrency networks, mining is a validation of transactions. For this effort, successful miners obtain new cryptocurrency as a reward. The reward decreases transaction fees by creating a complementary incentive to contribute to the processing power of the network. The rate of generating hashes, which validate any transaction, has been increased by the use of specialized machines such as FPGAs and ASICs running complex hashing algorithms like SHA-256 and Scrypt. This arms race for cheaper-yet-efficient machines has been on since the day the first cryptocurrency, bitcoin, was introduced in 2009. However, with more people venturing into the world of virtual currency, generating hashes for this validation has become far more complex over the years, with miners having to invest large sums of money on employing multiple high performance ASICs. Thus the value of the currency obtained for finding a hash often does not justify the amount of money spent on setting up the machines, the cooling facilities to overcome the enormous amount of heat they produce, and the electricity required to run them.
But let’s take a step back. Satoshi Nakamoto, the founder of Bitcoin, ensured that there would ever only be 21 million Bitcoins in existence. He (or they) reached that figure by calculating that people would discover, or “mine,” a certain number of blocks of transactions each day.

After an era of excitement over the fintech industry’s potential to disrupt financial services, the impact is finally taking shape. For many startups, that disruption has been possible not just by taking up trendy tech, but also through collaborations with industry incumbents and by working…
Bitcoin is not just the original cryptocurrency that allowed almost a thousand cryptocurrencies to bloom, but also the king of all cryptocurrencies; Bitcoin currently has a market capitalization (number of coins multiplied by value of each coin) of over $57 billion, or roughly 45% of the value of the whole cryptocurrency market.
Monero is a secure, private and untraceable currency. This open source cryptocurrency was launched in April 2014 and soon spiked great interest among the cryptography community and enthusiasts. The development of this cryptocurrency is completely donation-based and community-driven. Monero has been launched with a strong focus on decentralization and scalability, and enables complete privacy by using a special technique called ‘ring signatures.’ With this technique, there appears a group of cryptographic signatures including at least one real participant – but since they all appear valid, the real one cannot be isolated.
Zcash, a decentralized and open-source cryptocurrency launched in the latter part of 2016, looks promising. “If Bitcoin is like http for money, Zcash is https,” is how Zcash defines itself. Zcash offers privacy and selective transparency of transactions. Thus, like https, Zcash claims to provide extra security or privacy where all transactions are recorded and published on a blockchain, but details such as the sender, recipient, and amount remain private. Zcash offers its users the choice of ‘shielded’ transactions, which allow for content to be encrypted using advanced cryptographic technique or zero-knowledge proof construction called a zk-SNARK developed by its team. (Related reading, see: What Is Zcash?)
However, not everyone switched over to the “new” Ethereum fork because they still believed in Ethereum’s original promise of standing against financial corruption and changes to the network based on a human’s whim. To them, this is what the new Ethereum became when the developers decided to essentially “bail out” the DAO and saved it from the hacker by forking the entire platform.

Wallet generation centralized????? Can’t we make a wallet by flipping a coin 256 times? How will they stop that? And you do realize that they can’t own all the wallet addresses. There’s like, for all intents and purposes to a human, infinite wallet addresses
This danger exists in large part because grasping even the basics of blockchain technology remains daunting for non-specialists. In a nutshell, blockchains link together a global swarm of servers that hosts thousands of copies of the system’s transaction records. Server operators constantly monitor one another’s records, meaning that to steal money or otherwise alter the ledger, a hacker would have to compromise many machines across a vast network in one fell swoop. Even as the global banking system faces relentless cyberattacks, the more than $30 billion in value on Bitcoin’s blockchain has proven essentially immune to hacking.

Isn’t there something out there in place to protect my potentially fake investment? Truth be told, you are sort of out of luck. You see, most of these ICO coin tokens are designed in a way that marks them as ‘software presale tokens.’ So essentially, your ICO coins are no different than a video game token that you bought before it launched. The main reason many developers choose to address their new currency in such a way is to avoid paying all the expenses that come alongside legal sales. In a similar matter, a developer of a newfound cryptocurrency might choose to say that his or her investors are ‘donating’ coins to their cause and what not. So while this is completely acceptable and falls under the same reasoning for why Bitcoin was invented in the first place, to decentralize and stop all the crazy fees that go into making these investments happen, it’s still relatively questionable.
So far, efforts to regulate digital currency have been minimal. But central banks are getting interested in studying ledgers that make it possible for them to use Bitcoins in much the same way they store gold, currencies, and other assets (except they would have to collect and store cryptocurrencies digitally). On top of that, major banks are becoming interested in digital currencies. Mizuho Bank is currently looking into a digital currency developed with IBM Japan.
Just like confederate money, these too will soon be worthless. That’s what happens when there’s nothing to back it. So much for your ‘free money’. Maybe now people will actually be able to use (and afford) video cards for what they’re originally intended for instead of paying 200%+ prices for them.
Problem is, Bitcoins can be stolen in huge quantities, just like money, and with no centralized bank, there’s no way to recoup the losses. There are several types of Bitcoin ATMs, which exchange Bitcoins for flat currencies. Most machines are expensive and rare, ranging from $5,000 to $2,000. Skyhook, a Portland, Oregon-based company, demoed a $1,000, machine at a conference this month. It is the first portable, open source ATM.
Now if you are interested in investing in Bitcoins or digital currencies, this probably isn’t the post for you. What we plan on explaining to you is the societal implications of such technology being implemented at scale.
Cryptocurrencies make it easier to transfer funds between two parties in a transaction; these transfers are facilitated through the use of public and private keys for security purposes. These fund transfers are done with minimal processing fees, allowing users to avoid the steep fees charged by most banks and financial institutions for wire transfers.
