For those of you who have not been paying attention to one of the biggest trends in investing and tech, cryptocurrencies are digital currencies using encryption techniques that regulate the generation of currency and verify the transfer of funds, operating independently of a central bank. Units of currency are created through a process referred to as mining.
While it’s very easy to buy Bitcoins - there are numerous exchanges in existence that trade in BTC - other cryptocurrencies aren’t as easy to acquire. Although, this situation is slowly improving with major exchanges like Kraken, BitFinex, BitStamp and many others starting to sell Litecoin, Ethereum, Monero, Ripple and so on. There are also a few other different ways of being coin, for instance, you can trade face-to-face with a seller or use a Bitcoin ATM.
The one and only, the first and most famous cryptocurrency. Bitcoin serves as a digital gold standard in the whole cryptocurrency-industry, is used as a global means of payment and is the de-facto currency of cyber-crime like darknet markets or ransomware. After seven years in existence, Bitcoin‘s price has increased from zero to more than 650 Dollar, and its transaction volume reached more than 200.000 daily transactions.

Darknet markets present challenges in regard to legality. Bitcoins and other forms of cryptocurrency used in dark markets are not clearly or legally classified in almost all parts of the world. In the U.S., bitcoins are labelled as "virtual assets". This type of ambiguous classification puts pressure on law enforcement agencies around the world to adapt to the shifting drug trade of dark markets.[75]

是Cryptocurrency安全


The semi-anonymous nature of cryptocurrency transactions makes them well-suited for a host of nefarious activities, such as money laundering and tax evasion. However, cryptocurrency advocates often value the anonymity highly. Some cryptocurrencies are more private than others. Bitcoin, for instance, is a relatively poor choice for conducting illegal business online, and forensic analysis of bitcoin transactions has led authorities to arrest and prosecute criminals. More privacy-oriented coins do exist, such as Dash, ZCash, or Monero, which are far more difficult to trace.

The first decentralized cryptocurrency, bitcoin, was created in 2009 by pseudonymous developer Satoshi Nakamoto. It used SHA-256, a cryptographic hash function, as its proof-of-work scheme.[14][15] In April 2011, Namecoin was created as an attempt at forming a decentralized DNS, which would make internet censorship very difficult. Soon after, in October 2011, Litecoin was released. It was the first successful cryptocurrency to use scrypt as its hash function instead of SHA-256. Another notable cryptocurrency, Peercoin was the first to use a proof-of-work/proof-of-stake hybrid.[16]

don’t use coinbase. They held my funds and I couldn’t use my bitcoins until their value dropped by 1/4. this company is awful. I verified my ID, bank account, email, and everything and they lied and said initially it takes 3-4 days for funds to be available. once the bought the bitcoin they said it will take one week. and that is still a lie because after one week the funds are NOT available. liars !!!!

Many people believe that cryptocurrencies are the hottest investment opportunity currently available. Indeed, there are many stories of people becoming millionaires through their Bitcoin investments. Bitcoin is the most recognizable digital currency to date, and just last year one BTC was valued at $800. In November 2017, the price of one Bitcoin exceeded $7,000.
Transactions that occur through the use and exchange of these altcoins are independent from formal banking systems, and therefore can make tax evasion simpler for individuals. Since charting taxable income is based upon what a recipient reports to the revenue service, it becomes extremely difficult to account for transactions made using existing cryptocurrencies, a mode of exchange that is complex and difficult to track.[66]

NEM — Unlike most other cryptocurrencies that utilize a Proof of Work algorithm, it uses Proof of Importance, which requires users to already possess certain amounts of coins in order to be able to get new ones. It encourages users to spend their funds and tracks the transactions to determine how important a particular user is to the overall NEM network.

In August 2019, Coinbase announced that it was targeted by a sophisticated hacking attack attempt in mid-June. This reported attack used spear-phishing and social engineering tactics (including sending fake e-mails from compromised email accounts and created a landing page at the University of Cambridge) and two Firefox browser zero-day vulnerabilities. One of the Firefox vulnerabilities could allow an attacker to escalate privileges from JavaScript on a browser page (CVE-2019–11707) and the second one could allow the attacker to escape the browser sandbox and execute code on the host computer (CVE-2019–11708). Coinbase's security team detected and blocked the attack, the network was not compromised, and no cryptocurrency was stolen.[39][40][41]

到底是什么Blockchain


In May 2018, Bitcoin Gold (and two other cryptocurrencies) were hit by a successful 51% hashing attack by an unknown actor, in which exchanges lost estimated $18m.[citation needed] In June 2018, Korean exchange Coinrail was hacked, losing US$37 million worth of altcoin. Fear surrounding the hack was blamed for a $42 billion cryptocurrency market selloff.[72] On 9 July 2018 the exchange Bancor had $23.5 million in cryptocurrency stolen.[73]
比特币与莱特币都采用了区块链技术,且都有51%攻击的问题。它们采用区块链技术,所有历史记录按照时间先后顺序,打包成一个个单独的区块,再把这些单独的区块链接在一起形成一个总账本 [5]  。这些区块内除了包含交易记录外,还包含新发行的莱特币和交易的手续费,这两笔钱支付给挖矿的矿工作为酬劳。无论谁挖到该区块,那么该区块内含有的新发行的莱特币和交易的手续费这两笔钱都归挖到者,以鼓励矿工积极参与结算。区块链技术容易产生51%攻击的问题:无论任何组织甚至个人,只要掌控某一种基于区块链原理的虚拟货币的全部运算能力的51%,这个人或组织就能够任意操纵该虚拟货币的所有交易。如果区块链只认运算能力最大者,谁的运算能力最大,谁就能抢到下一个区块,如果某个个人或组织掌控了全部运算能力的51%,那就意味着没人比他运算能力更强,故而他就可以随意操纵。所以,对于基于区块链原理的虚拟货币,参与挖矿的越多就越健壮,运算能力越分散就越健壮;挖坑者越少越脆弱,运算能力越集中就越脆弱,矿池越集中也就越脆弱 [1]  。

Coinbase has two core products: a Global Digital Asset Exchange (GDAX) for trading a variety of digital assets on its professional asset trading platform, and a user-facing retail broker of Bitcoin, Bitcoin Cash, Ether, Ethereum Classic, and Litecoin for fiat currency.[24] It also offers an API for developers and merchants to build applications and accept payments in both digital currencies. As of 2018, the company offered buy/sell trading functionality in 32 countries,[42] while the cryptocurrency wallet was available in 190 countries worldwide.[43] On March 26, 2018, Coinbase announced their intention to add support for ERC-20 tokens.[44]

Homero Josh Garza, who founded the cryptocurrency startups GAW Miners and ZenMiner in 2014, acknowledged in a plea agreement that the companies were part of a pyramid scheme, and pleaded guilty to wire fraud in 2015. The U.S. Securities and Exchange Commission separately brought a civil enforcement action against Garza, who was eventually ordered to pay a judgment of $9.1 million plus $700,000 in interest. The SEC's complaint stated that Garza, through his companies, had fraudulently sold "investment contracts representing shares in the profits they claimed would be generated" from mining.[70]

In 1983, the American cryptographer David Chaum conceived an anonymous cryptographic electronic money called ecash.[7][8] Later, in 1995, he implemented it through Digicash,[9] an early form of cryptographic electronic payments which required user software in order to withdraw notes from a bank and designate specific encrypted keys before it can be sent to a recipient. This allowed the digital currency to be untraceable by the issuing bank, the government, or any third party.

“If the trend continues, the average person will not be able to afford to purchase one whole bitcoin in 2 years. As global economies inflate and markets exhibit signs of recession, the world will turn to Bitcoin as a hedge against fiat turmoil and an escape against capital controls. Bitcoin is the way out, and cryptocurrency as a whole is never going away, it’s going to grow in use and acceptance as it matures.”

So the app is pretty great when it comes to buying crypto, they can give you the funds immediately at the current price of the crypto, so high purchasing fees and selling it on a quick time line are virtually non existent when you are making small orders, most likely biggers as well. Not so fast... if you purchased it through your bank, because the allowance is higher on it than 25$ for a new card, your funds are basically frozen for 2 weeks. You can not cash out, nor you can send crypto to another wallet, so if you are looking for something to transaction with this isn’t the greatest app to do it with. I’m stuck with funds frozen for already 10 days, and now I have to wait another 5 for the banks to clear it, when on the card is faster, but you are stuck with the same high cost for selling it which comes out to bite you in the but for the fees. Yes, I can sell it and wait at usd wallet so the price doesn’t fluctuate, but again, if you want to get the funds out they are the power delay and have no intention to speed the process and again, you are in lala land waiting for it! Before, it’s not used be this bad but seems like delays and restrictions will expand. For the high cost of buying, and buying always at a higher price than it actually is, it makes even more worthless, even waisting time and resources just on trying to obtain some btc. There are better apps and cheaper apps that don’t cause you such issues. Good luck crypto fans

Blockchains are secure by design and are an example of a distributed computing system with high Byzantine fault tolerance. Decentralized consensus has therefore been achieved with a blockchain.[29] Blockchains solve the double-spending problem without the need of a trusted authority or central server, assuming no 51% attack (that has worked against several cryptocurrencies).
Bitcoin is pseudonymous rather than anonymous in that the cryptocurrency within a wallet is not tied to people, but rather to one or more specific keys (or "addresses").[41] Thereby, bitcoin owners are not identifiable, but all transactions are publicly available in the blockchain. Still, cryptocurrency exchanges are often required by law to collect the personal information of their users.[citation needed]
As of February 2018, the Chinese Government halted trading of virtual currency, banned initial coin offerings and shut down mining. Some Chinese miners have since relocated to Canada.[32] One company is operating data centers for mining operations at Canadian oil and gas field sites, due to low gas prices.[33] In June 2018, Hydro Quebec proposed to the provincial government to allocate 500 MW to crypto companies for mining.[34] According to a February 2018 report from Fortune,[35] Iceland has become a haven for cryptocurrency miners in part because of its cheap electricity. Prices are contained because nearly all of the country's energy comes from renewable sources, prompting more mining companies to consider opening operations in Iceland.[citation needed]

According to PricewaterhouseCoopers, four of the 10 biggest proposed initial coin offerings have used Switzerland as a base, where they are frequently registered as non-profit foundations. The Swiss regulatory agency FINMA stated that it would take a "balanced approach" to ICO projects and would allow "legitimate innovators to navigate the regulatory landscape and so launch their projects in a way consistent with national laws protecting investors and the integrity of the financial system." In response to numerous requests by industry representatives, a legislative ICO working group began to issue legal guidelines in 2018, which are intended to remove uncertainty from cryptocurrency offerings and to establish sustainable business practices.[50]

Take the money on your bank account: What is it more than entries in a database that can only be changed under specific conditions? You can even take physical coins and notes: What are they else than limited entries in a public physical database that can only be changed if you match the condition than you physically own the coins and notes? Money is all about a verified entry in some kind of database of accounts, balances, and transactions.

Coinbase is a terrible and unprofessional company. They’ve ignored my requests for escalation after providing no feed back on the issues I am having. These issues are costing this customer not only monetarily, but due to the lack of transparency with new policies in which coinbase will hold your funds hostage for 10 days while advising that it can be transferred “instantly” is not only false, but malicious contempt.

Essentially, if you are interested in trading in digital currencies but don't want to get bogged down in the underlying technology, products like Coinbase are a way to begin a foray into a new form of currency speculation and investing. You do, however, lose some of the advantages of trading in a cryptocurrency and through the blockchain. On Coinbase, you have no pseudo anonymity—your name is attached to your Coinbase account and so is your bank account, so transaction history is relatively easy to track down. And if you're not working on the blockchain, there's not much you can do to ensure that the verification of your transaction history or your account is taking place on the blockchain. You are, instead, placing trust in the intermediary, in this case, Coinbase.

NO WAY. How do some many people trust Coinbase with their money When their website’s software is full of faulty programs that they won’t or can’t fix. IE, I tried to add a new debit card to my account. I gave them my cards info and was told to check my account for two small charges made by coinbase and enter the amounts in a designated page. Both amounts were over $3.00, but the verification page only allowed me to submit amounts under $2.00. I was never able to add another card to my account. For me, no big deal,… Read more »
To understand the revolutionary impact of cryptocurrencies you need to consider both properties. Bitcoin as a permissionless, irreversible, and pseudonymous means of payment is an attack on the control of banks and governments over the monetary transactions of their citizens. You can‘t hinder someone to use Bitcoin, you can‘t prohibit someone to accept a payment, you can‘t undo a transaction.

There are several different types of cryptocurrency wallets that cater for different needs. If your priority is privacy, you might want to opt for a paper or a hardware wallet. Those are the most secure ways of storing your crypto funds. There are also ‘cold’ (offline) wallets that are stored on your hard drive and online wallets, which can either be affiliated with exchanges or with independent platforms.

One of the most important problems that any payment network has to solve is double-spending. It is a fraudulent technique of spending the same amount twice. The traditional solution was a trusted third party - a central server - that kept records of the balances and transactions. However, this method always entailed an authority basically in control of your funds and with all your personal details on hand.

Depending on a jurisdiction you live in, once you’ve made a profit or a loss investing in cryptocurrencies, you might need to include it in your tax report. In terms of taxation, cryptocurrencies are treated very differently from country to country. In the US, the Internal Revenue Service ruled that Bitcoins and other digital currencies are to be taxed as property, not currency. For investors, this means that accrued long-term gains and losses from cryptocurrency trading are taxed at each investor’s applicable capital gains rate, which stands at a maximum of 15 percent.
Within a cryptocurrency network, only miners can confirm transactions by solving a cryptographic puzzle. They take transactions, mark them as legitimate and spread them across the network. Afterwards, every node of the network adds it to its database. Once the transaction is confirmed it becomes unforgeable and irreversible and a miner receives a reward, plus the transaction fees.
Essentially, any cryptocurrency network is based on the absolute consensus of all the participants regarding the legitimacy of balances and transactions. If nodes of the network disagree on a single balance, the system would basically break. However, there are a lot of rules pre-built and programmed into the network that prevents this from happening.

Zcoin is a privacy focused cryptocurrency that was originally built on the Zerocoin protocol. However, given a number of vulnerabilities in that protocol, they recently moved to a new "Sigma" Protocol that was launched in 2019. Transactions are made private by a privacy enhancement in the protocol called "minting". Before you are able to send transactions, you have to mint new coins. Given that all coin’s transactions originate from a newly minted coin, it is hard to track the origin. Privacy on Zcoin is made possible through the use of Zero Knowledge proofs. You also have Tor integration as well as their recently released "Dandelion" protocol. This will further help to cement user privacy on the network. ZCoin uses a the Merkle Tree Proof of Work algorithm (MTP). This is a memory hard algorithm that is considered to be ASIC resistant and hence less prone to centralisation. Zcoin also has a masternode architecture with their "Znodes" (require 1,000 XZC to stake). In compensation for running this full node, the Znode will receive 30% of the newly minted Zcoins. The team behind the Zcoin protocol is quite extensive experience in blockchain engineering, software development, cryptography and many more. The developers have also been hard at work if you take a look into their GitHub repository. When it comes to markets, XZC is listed on a number of exchanges including MXC, Coinex, Binance, Huobi etc. There appears to be reasonable liquidity on these exchanges which will ease execution. However, XZC is still volatile so trade with caution. *Coin Bureau's views are not investment advice. Do Your Own Research.
