Economics of bitcoin

4 stars based on 36 reviews

All eyes in the world of sports pitino bitcoin wikipedia morning are focused pitino bitcoin wikipedia on the Commonwealth of Kentucky, where there appears to be a preponderance of evidence that the University of Louisville organized private sex shows for basketball recruits. There is one figure that is even more polarizing within the context of this rivalry, and his name is Rick Pitino.

He led Kentucky to an NCAA title in and a runner-up finish inand then fled for the greener pastures of the NBA, only to return to college coaching with his tail between his legs after massive failures in both Boston and New York.

When he returned, however, he returned to the one school that UK fans could never forgive him for choosing—their archenemy, Louisville. Even worse, he turned Louisville into a national power again, winning a title in It looks like he may have done it using some less-than-wholesome methods, pitino bitcoin wikipedia.

Pitino has, thus pitino bitcoin wikipedia, claimed ignorance of the entire situation. After all, this is the man who previously survived the Karen Sypher extortion scandal. He claims to have had no knowledge of this latest scandal, that it was all perpetrated by Andre McGee, a former player, assistant, and Director of Basketball Operations at Louisville. These hostesses are university students who are given the responsibility of making sure that the recruit enjoys himself.

And pitino bitcoin wikipedia was twenty years ago, when our young people were much less sexualized than kids coming out pitino bitcoin wikipedia high school today are. In fact, I suspect that the reason that the U of L took this path was to keep the exploits from becoming public through social media. And, frankly, I prefer that they bring in professionals rather than have college girls act as unpaid hookers.

So, much like the Joe Paterno scandal, I suspect that it will all come down to what Pitino knew, and when he knew it. Or, at least we thought we did. We all saw what happened to Paterno. Once again, it all pitino bitcoin wikipedia down to winning. Pitino survived the Sypher scandal, and then promptly brought a title to Cardinal Nation. However, when you hang banners, it gets trickier. If the University, either directly or indirectly, provided alcohol and sex to high school juniors and seniors, everybody involved has to go, from the AD down.

The culture surrounding college and in many cases high school sports is utterly bewildering. Sooner or later something will happen that is big enough to bring it all down. I thought Penn State would have been that event, but I guess not. Oklahoma State basically using coeds as prostitutes to recruit top athletic talent. Some pitino bitcoin wikipedia from a dude I know who commented on that story:. Lots of college girls will fuck anyone that will stand still long enough.

Money, power, networking, the lot. And all they have to do to get access to this world is help recruit top athletic talent. Usually top male athletic talent. And do you know how you impress an 18 year old, who as we all can pitino bitcoin wikipedia from our youth is basically just a life support system for a perpetual hard-on?

A threesome is a fucking awesome start. Those girls have plenty of self esteem. And, hey…he might even be cute and funny. These chicks were making one hell of a bargain. They were getting access to the upper echelons of society for doing nothing more than what a bunch of other girls on the campus are doing anyway. Some for things as low as grades or personal use pot.

Hell, buddy of mine busted a pitino bitcoin wikipedia who was making so much money at a college that he priced in sexual favors from the cute girls buying from him. The girls luring the football players with their feminine pitino bitcoin wikipedia and getting the finest perks the university could offer were making a MUCH better pitino bitcoin wikipedia.

Welcome to higher education, folks. These girls were using their assets to leverage themselves into a better position. Same as it ever was, same as it ever shall be. Everybody involved knew the score. The athletes played ball. The girls helped recruit the athletes with sex. The people buying boxes at the stadium cheered it all on. The university officials cashed the checks. You seem to understand politics and sexuality better than any random pseudonymous commenter I can recall having seen in some time.

Get a blog wouldja! Now I haven't seen a picture of your daughter, but in the unlikely chance that she's even physically qualified to be a Gator Getter, let her work to her strengths and hope for the best, whatever that may mean to her. Bark pitino bitcoin wikipedia Jack may be quasi-public, internet famous figures, but that is the kind of thing that can earn you a punch in the mouth IRL.

The kind of thing! Good thing I have this sooper sekrit pseudonym to protect me from pugilistic internet vigilantes eh. So Jack, tertium non datur? Bark btw is that short for Bartholomew? The reality of pitino bitcoin wikipedia a Gator Getter is somewhere in between the two scenarios. My suggestion is that it is much closer to the unpleasant one. The modern football-machine university promises a lot of opportunities to a lot of young men and women.

A very minor percentage of the people who sign on the dotted line have anything but sorrow to show for it. Pitino bitcoin wikipedia machine eats flesh by the ton in exchange for the money of the alumni and the television channels. What I would suggest is that the university takes young women from very sheltered backgrounds, fills their heads full of the supposedly glory and excitement of sexually serving men who are often very confused and upset and experiencing some authentic fish-out-of-water moments, and then lets the cash register ring while nature takes its pitino bitcoin wikipedia.

In all likelihood, neither set has the mental faculties nor the inclinations for white collar professional careers, pitino bitcoin wikipedia instead of being carpenters and waitresses, they're shooting for the stars. That so many of them miss the mark and die trying if only figuratively is why society respects and envies the ones who actually hit their intended targets and hustle their way into the limelight, however briefly.

Because being smart is bad mkay. I mean, how are you even supposed to have conversations with smart peoples?!!! Or go breath through your mouth somewhere else. The smart UK fans are not gloating too much. Their coach does not have the cleanest of records technically he never reached a Pitino bitcoin wikipedia Four before with UK.

Nothing surprises me anymore. It seems reasonable to conclude that everyone involved with college and professional sports is a scumbag until proven otherwise, especially college.

That largely stems from the guys running the programs, Tom Izzo and Bo Ryan. I may think Bo Ryan is a vampire that is dead set on ruining college basketball, but he runs a clean program. Instead, we live in the Internet age, where fools reveal themselves to the world, without any need for finding and exposing them. People like you are a blight on civil discourse, and upon freedom of opinion. Your pitino bitcoin wikipedia minded smug self assurance stands out like a sore thumb.

So you may not really be that bad a person. But you still seem to have an axe to grind about college and pro sports, and a misguided view of JoePa though I should be more understanding of that, considering the hatchet job that was done to him by the Penn State admin, to protect themselves, and the press, pitino bitcoin wikipedia aggrandize the individuals waving their banners righteously.

No, Disinterested Observer, not everyone who molests children looks or acts like Krusty the Clown. Sandusky had a pitino bitcoin wikipedia of other people fooled for a long time, pitino bitcoin wikipedia some powerful civic leaders in central PA, and a lot of parents.

I doubt that every one of those parents was pimping out their children in the hope that Sandusky would turn them into million dollar athletes. And there were rumors, and apparently something was observed, or suspected, because Paterno HAD fired Sandusky many years before. It was the admins who agreed to let him have the same privileges other former high ranking university personnel enjoyed, the right to continue using any and all University facilities.

Paterno had had nothing to do with Sandusky for about at least a decade prior to his arrest. And the university pitino bitcoin wikipedia, and even a later state investigation, tried to downplay the responsibility of the school as a whole, and its leadership. There was pitino bitcoin wikipedia evidence that he had voiced some concerns to upper management at Penn State, and they told him that they would follow up on it, and that he should not act. I used to like Penn State football.

One of a handful of college football programs I liked just because of what they were and what they stood for. I could be wrong but it is my understanding that due to the success of the football program Paterno was co-equal if not superior to any administrator there up to and including the president. Point 1 I have never seen any evidence that showed that Paterno had any knowledge of what Sandusky was doing.

The sole exception as an ex post facto case of fingerpointing by one former graduate athletic assistant who had been named as being aware, and he claimed that he had reported it to Paterno. And since you accuse me of supporting a pitino bitcoin wikipedia molester, without any evidence to support your assertions about either me or JoePa, there is something seriously wrong with you. Serious issues pitino bitcoin wikipedia as child molestation are harmed, not pitino bitcoin wikipedia, by witch hunting…and you have added to that harm by your mindless assertions.

How about one bit of proof from testiimony under oath by anyone other than the university officials over Paterno or that sleazy athletic assistant who admitted he knew, and when he found it it was a crime not to have reported it, swore that he had told Paterno. Neither he nor the admins did anything about it, until they pitino bitcoin wikipedia under the gun. Then they picked on an old man who was dying from cancer.

I have easily read dozens of articles and depositions in their entiretyso I am not just speaking out of personal sentiment or ignorance. Where did you get your facts and what are they, and their source? Or do you have none, only your feeling that somehow, he must have been involved. Any parent pitino bitcoin wikipedia that if their child pitino bitcoin wikipedia to do something that they disapprove of badly pitino bitcoin wikipedia, they will find a way to do it.

But parents also know that they are duty bound to make their best effort to convince their children to avoid behaviors and experiences that they sincerely believe will be harmful to them, and that the parent might pitino bitcoin wikipedia better aware of than pitino bitcoin wikipedia child is.

Bitcoin group mining

Bitcoin was invented by an unknown person or group of people under the name Satoshi Nakamoto [10] and released as open-source software in Bitcoins are created as a reward for a process known as mining.

They can be exchanged for other currencies, [12] products, and services. As of February , over , merchants and vendors accepted bitcoin as payment. The word bitcoin first occurred and was defined in the white paper [5] that was published on 31 October There is no uniform convention for bitcoin capitalization. Some sources use Bitcoin , capitalized, to refer to the technology and network and bitcoin , lowercase, to refer to the unit of account.

The unit of account of the bitcoin system is a bitcoin. Named in homage to bitcoin's creator, a satoshi is the smallest amount within bitcoin representing 0. As with most new symbols, font support is very limited. Typefaces supporting it include Horta. On 18 August , the domain name "bitcoin. In January , the bitcoin network came into existence after Satoshi Nakamoto mined the first ever block on the chain, known as the genesis block. This note has been interpreted as both a timestamp of the genesis date and a derisive comment on the instability caused by fractional-reserve banking.

The receiver of the first bitcoin transaction was cypherpunk Hal Finney , who created the first reusable proof-of-work system RPOW in In the early days, Nakamoto is estimated to have mined 1 million bitcoins. So, if I get hit by a bus, it would be clear that the project would go on. Over the history of Bitcoin there have been several spins offs and deliberate hard forks that have lived on as separate blockchains.

These have come to be known as "altcoins", short for alternative coins, since Bitcoin was the first blockchain and these are derivative of it. These spin offs occur so that new ideas can be tested, when the scope of that idea is outside that of Bitcoin, or when the community is split about merging such changes.

Since then there have been numerous forks of Bitcoin. See list of bitcoin forks. The blockchain is a public ledger that records bitcoin transactions. A novel solution accomplishes this without any trusted central authority: The blockchain is a distributed database — to achieve independent verification of the chain of ownership of any and every bitcoin amount, each network node stores its own copy of the blockchain.

This allows bitcoin software to determine when a particular bitcoin amount has been spent, which is necessary in order to prevent double-spending in an environment without central oversight. Whereas a conventional ledger records the transfers of actual bills or promissory notes that exist apart from it, the blockchain is the only place that bitcoins can be said to exist in the form of unspent outputs of transactions.

Transactions are defined using a Forth -like scripting language. When a user sends bitcoins, the user designates each address and the amount of bitcoin being sent to that address in an output. To prevent double spending, each input must refer to a previous unspent output in the blockchain. Since transactions can have multiple outputs, users can send bitcoins to multiple recipients in one transaction. As in a cash transaction, the sum of inputs coins used to pay can exceed the intended sum of payments.

In such a case, an additional output is used, returning the change back to the payer. Paying a transaction fee is optional. Because the size of mined blocks is capped by the network, miners choose transactions based on the fee paid relative to their storage size, not the absolute amount of money paid as a fee. The size of transactions is dependent on the number of inputs used to create the transaction, and the number of outputs.

In the blockchain, bitcoins are registered to bitcoin addresses. Creating a bitcoin address is nothing more than picking a random valid private key and computing the corresponding bitcoin address. This computation can be done in a split second. But the reverse computing the private key of a given bitcoin address is mathematically unfeasible and so users can tell others and make public a bitcoin address without compromising its corresponding private key. Moreover, the number of valid private keys is so vast that it is extremely unlikely someone will compute a key-pair that is already in use and has funds.

The vast number of valid private keys makes it unfeasible that brute force could be used for that. To be able to spend the bitcoins, the owner must know the corresponding private key and digitally sign the transaction.

The network verifies the signature using the public key. If the private key is lost, the bitcoin network will not recognize any other evidence of ownership; [8] the coins are then unusable, and effectively lost. Mining is a record-keeping service done through the use of computer processing power.

To be accepted by the rest of the network, a new block must contain a so-called proof-of-work PoW. Every 2, blocks approximately 14 days at roughly 10 min per block , the difficulty target is adjusted based on the network's recent performance, with the aim of keeping the average time between new blocks at ten minutes. In this way the system automatically adapts to the total amount of mining power on the network.

The proof-of-work system, alongside the chaining of blocks, makes modifications of the blockchain extremely hard, as an attacker must modify all subsequent blocks in order for the modifications of one block to be accepted.

Computing power is often bundled together or "pooled" to reduce variance in miner income. Individual mining rigs often have to wait for long periods to confirm a block of transactions and receive payment.

In a pool, all participating miners get paid every time a participating server solves a block. This payment depends on the amount of work an individual miner contributed to help find that block.

The successful miner finding the new block is rewarded with newly created bitcoins and transaction fees. To claim the reward, a special transaction called a coinbase is included with the processed payments. The bitcoin protocol specifies that the reward for adding a block will be halved every , blocks approximately every four years. Eventually, the reward will decrease to zero, and the limit of 21 million bitcoins [f] will be reached c.

Their numbers are being released roughly every ten minutes and the rate at which they are generated would drop by half every four years until all were in circulation. A wallet stores the information necessary to transact bitcoins. While wallets are often described as a place to hold [59] or store bitcoins, [60] due to the nature of the system, bitcoins are inseparable from the blockchain transaction ledger.

A better way to describe a wallet is something that "stores the digital credentials for your bitcoin holdings" [60] and allows one to access and spend them. Bitcoin uses public-key cryptography , in which two cryptographic keys, one public and one private, are generated.

There are three modes which wallets can operate in. They have an inverse relationship with regards to trustlessness and computational requirements. Third-party internet services called online wallets offer similar functionality but may be easier to use. In this case, credentials to access funds are stored with the online wallet provider rather than on the user's hardware.

A malicious provider or a breach in server security may cause entrusted bitcoins to be stolen. An example of such a security breach occurred with Mt. Physical wallets store offline the credentials necessary to spend bitcoins. Another type of wallet called a hardware wallet keeps credentials offline while facilitating transactions.

The first wallet program — simply named "Bitcoin" — was released in by Satoshi Nakamoto as open-source code. While a decentralized system cannot have an "official" implementation, Bitcoin Core is considered by some to be bitcoin's preferred implementation. Bitcoin was designed not to need a central authority [5] and the bitcoin network is considered to be decentralized.

In mining pool Ghash. The pool has voluntarily capped their hashing power at Bitcoin is pseudonymous , meaning that funds are not tied to real-world entities but rather bitcoin addresses. Owners of bitcoin addresses are not explicitly identified, but all transactions on the blockchain are public.

In addition, transactions can be linked to individuals and companies through "idioms of use" e. To heighten financial privacy, a new bitcoin address can be generated for each transaction. Wallets and similar software technically handle all bitcoins as equivalent, establishing the basic level of fungibility.

Researchers have pointed out that the history of each bitcoin is registered and publicly available in the blockchain ledger, and that some users may refuse to accept bitcoins coming from controversial transactions, which would harm bitcoin's fungibility. The blocks in the blockchain were originally limited to 32 megabyte in size. The block size limit of one megabyte was introduced by Satoshi Nakamoto in , as an anti-spam measure. Transactions contain some data which is only used to verify the transaction, and does not otherwise effect the movement of coins.

SegWit introduces a new transaction format that moves this data into a new field in a backwards-compatible way. The segregated data, the so-called witness , is not sent to non-SegWit nodes and therefore does not form part of the blockchain as seen by legacy nodes. This lowers the size of the average transaction in such nodes' view, thereby increasing the block size without incurring the hard fork implied by other proposals for block size increases.

Bitcoin is a digital asset designed by its inventor, Satoshi Nakamoto, to work as a currency. The question whether bitcoin is a currency or not is still disputed.

According to research produced by Cambridge University , there were between 2. The number of users has grown significantly since , when there were , to 1. In , the number of merchants accepting bitcoin exceeded , Reasons for this fall include high transaction fees due to bitcoin's scalability issues, long transaction times and a rise in value making consumers unwilling to spend it.

Merchants accepting bitcoin ordinarily use the services of bitcoin payment service providers such as BitPay or Coinbase. When a customer pays in bitcoin, the payment service provider accepts the bitcoin on behalf of the merchant, converts it to the local currency, and sends the obtained amount to merchant's bank account, charging a fee for the service.

Bitcoins can be bought on digital currency exchanges. According to Tony Gallippi , a co-founder of BitPay , "banks are scared to deal with bitcoin companies, even if they really want to". In a report, Bank of America Merrill Lynch stated that "we believe bitcoin can become a major means of payment for e-commerce and may emerge as a serious competitor to traditional money-transfer providers.
