fast bitcoin ● Scarcity: Bitcoin supply is scarce, and asymptotically approaches 21 million coins.GET UP TO $132All of a sudden, with Bitcoin, that’s trivially easy. Bitcoins have the nifty property of infinite divisibility: currently down to eight decimal places after the dot, but more in the future. So you can specify an arbitrarily small amount of money, like a thousandth of a penny, and send it to anyone in the world for free or near-free.60 bitcoin wechat bitcoin 5 bitcoin cryptocurrency trading bitcoin лохотрон Ethereumbitcoin установка bitcoin ads фонд ethereum rpg bitcoin investment bitcoin сеть ethereum

Financial institutions were the first to dip their feet in, but academia, governments and consulting firms have also studied the technology.install a node, and audit/verify every transaction with little more than a computer command.For these reasons, Bitcoin and other cryptocurrencies share some characteristics with precious metals. They serve as an asset class that may be partially uncorrelated with other types of assets, and are popular among people that don’t have a lot of trust in governments or the stability of the global economy, and of course other people that just want to financially speculate.wallet cryptocurrency Crypto-anarchism is an ideology that seeks to create and deploy information infrastructure that, by design, is unable to comply with authoritarian requests to break the participating individuals' secrecy of correspondence.Bitcoin cash

The network is operated primarily by one incorporated entity.
Any component of its software is proprietary.
Decisions about code commits are closed to outside contributors.
Development process is private; only insiders know how decisions are made.
The project is free and open source, but multiple implementations are politically unviable.
Obstacles to altcoin competition
Bitcoin is a complex codebase which contains 12 years of brilliant engineering. Starting from scratch means re-encountering many of the same problems all over again; forking and attempting to work on an unfamiliar code base can mean endless frustration, as one learns its peculiarities. The biggest challenge to competing with Bitcoin is catching up to thousands of hours of contributions it has received.

Accelerating past the normal pace of open allocation requires some new tricks, because the usual speed-ups—raising money, paying fat salaries, and central planning often end up reducing developer draw and hardware draw, not increasing it.

DACs, or decentralized autonomous companies, are an attempt at overcoming this problem using the usual corporate carrots—resource planning, a salary and stable employment—but without the dreaded human managers. This may enable project velocity to increase without the introduction of undesirable qualities, but the efficacy of this approach remains to be seen.

DAC-operated cryptocurrency networks are interesting to the extent that they fulfill the following requirements:

Are similar to Bitcoin in architecture, with Proof-of-Work securing the base layer.
Coins are exchangeable for Bitcoin without a trusted central party in an “atomic swap.”
Is resistant to fork attacks from large ASIC miners, with plenty of hashrate or fork-resistant mechanisms.
Can use hybrid PoW/PoS to improve the fairness of human consensus.
Have some mechanism by which the contributor base may scale to the point where development velocity exceed Bitcoin’s.
Isn’t controlled by a dictator, which reduces the fun and freedom of open allocation, killing developer draw.
Has a talented team which can attract a lot of engineers and excitement to test limits of team scale.
Where value accumulates for investors
Who benefits from the forces at work in public cryptocurrency networks? The following points represent outstanding opportunities for capital.

Given:
Bitcoin is a self-organizing infrastructure project which provides flexible employment and intellectual stimulation for technologists.
Insight:
For these reasons, bitcoins themselves are valued collectibles within the technologist demographic, which is a critical and growing segment of the workforce. As infrastructure improves, perceived value increases.
Given:
Owing to Bitcoin’s 10-year head start and brilliant contributor base, its development will out-pace all but a few exceptionally competent projects. The few projects which survive will do so by innovating on top Bitcoin’s incentive model to speed development velocity without introducing technical debt, “catching up” with Bitcoin in functionality and network security.
Insight:
Over time, the entire value of the asset class will collapse into a select handful of undervalued cryptocurrencies, which have used DAC or hybrid consensus governance to increase project velocity to the point of competitiveness with Bitcoin.
Given:
In a large and secure cryptocurrency network, miners are equivalent to Galbraith’s shareholders: “irrelevant fixtures” to its development, but owners nonetheless.
Insight:
Mining OEMs, large-scale mine operators, and mining-related service providers will accumulate the vast majority of wealth created by Bitcoin and other cryptocurrency networks during the issuance period, despite expending far fewer human resources than the software developers who volunteer contributions.
Given:
The speed, cheap costs of operation, and settlement finality characteristic of “layer 2” point-to-point networks, built on top of base-layer cryptocurrencies, will make them ideal for retail and e-commerce payments as competitors to Visa, Mastercard, and Paypal. (Lightning Network has been well-explained already by others. )
Insight:
There will be many competing L2 networks built by both FOSS groups (such as Lightning) and private commercial interests (such as ICE). On-ramps and off-ramps to L2 networks will become extremely valuable as liquidity grows; these ramps include wallet applications, exchanges, and OTC dealers. Secondarily, these ramps will serve as natural portals for e-commerce activity.
Given:
As cryptocurrency transaction volume increases, major platforms like Apple iTunes and Google Play will continue to block cryptocurrency apps and digital collectibles from their devices, protecting their in-app Apple Pay and Google Pay purchasing frameworks, which developers on those platforms are required to use to sell digital goods. This payment-framework apartheid will create demand for third party privacy smartphones running Linux-based, GNU, or BSD operating systems, and which natively run cryptocurrency protocols. (Already, at least one such distribution has appeared.)
Insight:
After ASIC miners, smartphones will be the second most valuable category of cryptocurrency-specific devices whose prices are denominated in cryptocurrency. These devices will become highly-valued distribution and aggregation points for products and services offered by “entrepreneurial joiners” who integrate with, and build atop, Bitcoin and other networks.
Given:
Forced to compete with free software developed by large self-organizing masses of volunteers, and gaining nothing but unnecessary costs from their strict full-time hierarchy, major SAAS companies will suffer financially, forcing consolidation and layoffs. Many of these companies will launch competing “blockchain” based systems, but they will be too expensive and insecure for practical use. This may cause unexpected frustration for large software companies.
Insight:
We expect a private equity boom in the early 2020s, in which tokenized debt financing is used to finance a wave of hostile bust-up takeovers, unbundling large public technology companies, laying off elements of their technostructure, and reorganizing their teams to function autonomously on an open allocation basis. New digital financial products will be issued which entitle investors to streams of income from individual teams, products, or services within the formerly-unified company. In this way, public stocks will become baskets of “atomic equities” that represent the performance of each constituent unit in a given value chain; divisions between corporate entities and jurisdictions will cease to be relevant factors in the issuance of public and private securities. This activity will be pioneered by engineer-led investment groups, not incumbent underwriters, who will not be able to retain the necessary engineering talent to undertake such activities.

Things investors should generally avoid

Initial coin offerings (ICOs).
As we have discussed, cryptocurrency projects only qualify as good platforms for business if they earn volunteer contributions. Pre-minting tokens and selling them to “investors,” with a rich stash held back for the “team,” creates strong incentives for technical debt and command-and-control management which eventually drives out the best talent, crushing the utility of the network and the price of the coin.
ICO advisors and diversified ICO coin “funds.”
The market leader, Bitcoin, has exhibited extreme virality amongst software developers, miners, and retail investors. It has strong network effects. Very few projects will survive alongside Bitcoin, and they will be successful for reasons recounted in this essay—reasons that most ICO launchers would find surprising and counter-intuitive. Over-diversification will kill most cryptocurrency investment funds, who will miss out on market beta by holding too little bitcoin.
Venture-backed cryptocurrencies and private blockchains.
The 10-year investment horizon for venture capital funds limits long-term thinking, because companies are forced to dazzle investors each time they recapitalize. This “fundraising treadmill” feeds marketing narratives and “wow” features that generate technical debt. As we’ve learned, such systems cannot compete with the costs of open allocation non-commercial projects.
Categorizing coins for investment
In this paper we have discussed the context and origins of hacker culture, the free software movement, cypherpunks, and the currency system Bitcoin which is characteristic of these origins. We believe there are a substantial number of people who value Bitcoin strongly for the reasons mentioned.

Which coins are also valuable? Developing criteria from the narrative above is fairly straightforward. To someone who values Bitcoin, altcoins are valuable if it they meet the criteria in Section VI, but with alternative techniques. Coins become less valuable as they adhere more towards traditional, hierarchical, corporate software development processes.
The top-left quadrant:
A non-starter for investors; it is pure speculation on corporate-style projects which will inevitably rank lower in developer draw and higher in transaction costs, with more bugs and less stability than FOSS permissionless blockchains.
The lower-right quadrant:
Bitcoin appears here, along with similar open allocation FOSS forks of Bitcoin. While the fork may begin with one developer, others quickly join if they see differentiation characteristics in the new fork.
The lower-left quadrant:
Reflects the reality of many FOSS permissionless blockchains, which may have begun life in the lower-right quadrant. Ethereum seems to be migrating from the lower-right to the lower-left. These quadrants are generally investible, but the migration towards the lower-left is considered to be a negative attribute for a permissionless chain.
The top-right quadrant:
Meaningful attempts at innovation on top of Bitcoin are here, in the form of accelerating project velocity with automated governance, and without introducing the flaws of centralization (namely, technical debt and lack of open allocation). Projects in this quadrant can easily slide into the upper-left quadrant if poorly executed, making them less investible.
Conclusion: what is driving the cryptocurrency phenomenon?
Bitcoin has been largely characterized as a digital currency system built in protest to Central Banking. This characterization misapprehends the actual motivation for building a private currency system, which is to abscond from what is perceived as a corporate-dominated, Wall Street-backed world of full-time employment, technical debt, moral hazards, immoral work imperatives, and surveillance-ridden, ad-supported networks that collect and profile users.

To developers, adoption of Bitcoin and cryptocurrency symbolizes an exit (or partial exit) of the corporate-financial employment system in favor of open allocation work, done on a peer-to-peer basis, in exchange for a currency that is anticipated to increase in value.

Freelancing and solo entrepreneurship are already popular in Silicon Valley and amongst Millennial and Gen-X workers because these lifestyles afford them self-directed, voluntary work. Highly-skilled technology workers are already fed up with big tech, the drive for profit, and the spectre of technical debt. The leverage is increasingly on the side of the individual engineers; this is why the Uber executive quoted in the Preface fears the company may be “*****ed” if it “can’t hire any good engineers.”

This “exiting” of the mainstream employment system is why some members of the investor class may intuit Bitcoin as a threat:

If technologists exit the corporate-financial system en masse, the reduction in available technical labor would stymie the technical development of public companies, banks, and governments, whose services are increasingly digital.
If technologists build a cheap, private, and reliable “alternative financial system,” and if such a system cannot be regulated or taxed out of existence, then business activity will flow naturally into such a system to realize lower transaction costs. This draws value out of existing forex, equities, real assets, crushing the margins of existing financial services.
We believe these points provide critical insight into Warren Buffett’s classification of Bitcoin as “rat poison,” which is similar in tone to the reaction of Steve Ballmer to Linux, when he characterized it as a “cancer” that would destroy the Windows OS. To the administrators of expensive, proprietary monopolies, free and open source systems are deadly.

Charlie Munger’s assertion that cryptocurrencies are “turds,” also quoted in the Preface, is a more nuanced and less threatened reaction than his business partner’s. Cryptocurrency appears to be a “worse” currency system than the existing system, but it’s also clear that this “worse” substitute is interesting to ***** people; it simply confounds Munger that “worse is better” when a financial system is built in software instead of paper. He has probably never developed software, or encountered New Jersey Style, but that’s no fault of his.

Summary
For the last 50 years, technologists have been motivated to create a culture of software development that exists outside institutional boundaries. Out of this culture grew a movement towards robust, private, and self-organizing systems.

This vision is embodied in Bitcoin, which lays the groundwork for ways of working in information technology businesses, without a bureaucracy. Given what we know about the moral quality of the Cypherpunks’ struggle against institutional oversight, it’s easy to see why a sense of righteousness might be on display in the most fervent Bitcoin advocacy groups. In short, William Shatner got it right with his assessment in 2014

Far from being a novelty or prototype, Bitcoin has shown itself to be a threatening alternative to present-day organizational conventions and to the large commercial businesses that rely on them. It may spur a radical unbundling of corporate business as it lowers transaction costs for the institutions that adopt it. While the effects of such unbundling are unpredictable, value seems most likely to accumulate in cryptocurrency services businesses; in hardware makers and operators that rent computing resources to the network; and in building businesses on the layer 2 networks.

In the final part of this essay, we have looked at the potential impact of Bitcoin’s success, and expectations about its price. We’ve examined why most altcoins are doomed and we have provided guidance on investments to avoid, and hypothesized where value will accumulate for savvy allocators.

It’s tempting to think that the newest ICO or altcoin is the one that will finally 'improve' Bitcoin and fix all of its problems and that Bitcoin will be relegated to the dustbin of history due to its lack of some 'feature'. Indeed, nearly every altcoin, ICO or hardfork thinks that they’re being innovative in some fundamental way. What’s missed is that the biggest innovation has already happened.bitcoin carding ethereum сбербанк bitcoin playstation bitcoin community bitcoin location bitcoin история
