你如何Blockchain搜索


Hey to all. Since around 2 months, I am with 99bitcoins reading and getting info and I am very happy here, thanks for a good site. For my bad luck I did not check here for a review of coinbase, I would have save a lot of worthless time. To tell the truth, I hope there is a internet god out there and shut them down. I did not know about their support in US, but as I read the first reviews here, it seems they make themselves a pretty bad place there too. I am located in the D.R.,… Read more »

多少个比特币,每天开采


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]

这是最好的加密货币


         其原理是:假设两个使用IP协议的站点A、B通过第三层交换机进行通信,发送站点A在开始发送时,把自己的IP地址与B站的IP地址比较,判断B站是否与自己在同一子网内。若目的站B与发送站A在同一子网内,则进行二层的转发。若两个站点不在同一子网内,如发送站A要与目的站B通信,发送站A要向“缺省网关”发出ARP(地址解析)封包,而“缺省网关”的IP地址其实是三层交换机的三层交换模块。当发送站A对“缺省网关”的IP地址广播出一个ARP请求时,如果三层交换模块在以前的通信过程中已经知道B站的MAC地址,则向发送站A回复B的MAC地址。否则三层交换模块根据路由信息向B站广播一个ARP请求,B站得到此ARP请求后向三层交换模块回复其MAC地址,三层交换模块保存此地址并回复给发送站A,同时将B站的MAC地址发送到二层交换引擎的MAC地址表中。从这以后,当A向B发送的数据包便全部交给二层交换处理,信息得以高速交换。由于仅仅在路由过程中才需要三层处理,绝大部分数据都通过二层交换转发,因此三层交换机的速度很快,接近二层交换机的速度,同时比相同路由器的价格低很多。

谁真的发明了比特币


With the largest variety of markets and the biggest value - having reached a peak of 18 billion USD - Bitcoin is here to stay. As with any new invention, there can be improvements or flaws in the initial model however the community and a team of dedicated developers are pushing to overcome any obstacle they come across. It is also the most traded cryptocurrency and one of the main entry points for all the other cryptocurrencies. The price is as unstable as always and it can go up or down by 10%-20% in a single day.

可以比特币被复制


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 !!!!

多长时间才能让比特币


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]

为什么比特币值得这么多


In 2014, the company grew to one million users, acquired the blockchain explorer service Blockr and the web bookmarking company Kippt, secured insurance covering the value of bitcoin stored on their servers, and launched the vault system for secure bitcoin storage.[12][13][14] Throughout 2014, the company also formed partnerships with Overstock, Dell, Expedia, Dish Network, and Time Inc. allowing those firms to accept bitcoin payments.[15][16][17][18] The company also added bitcoin payment processing capabilities to the traditional payment companies Stripe, Braintree, and PayPal.[19]

我能买比特币在Blockchain


The platform stores 98% of customers funds offline to ensure the security of the cryptocurrency assets you purchase and store within Coinbase. On their website, Coinbase assures customers that "sensitive data that would normally reside on our servers is disconnected entirely from the internet." Data is then encrypted, and transferred to USB drives and paper backups, and distributed in safe deposit boxes vaults all over the world. 

什么是比特币的货币,它是如何工作的


Bitcoin (BTC) is the world’s first decentralized digital currency and payment system and is by far the most known and valuable cryptocurrency. It was created in 2009 by an anonymous person or group called Satoshi Nakamoto. Bitcoin enables transactions to be sent peer-to-peer without passing through a central authority. The transactions are recorded on a decentralized public ledger called the blockchain and each payment acquires a small transaction fee to cover the cost of the network. The total supply of Bitcoin is 21 million and it’s smallest unit of bitcoin is called a Satoshi, it’s a hundred millionth of a bitcoin – 0.00000001 BTC. The creation of Bitcoin’s is happening through mining. Miners have the task to validate transactions and keep the network secure. Their efforts are rewarded by new minted Bitcoins and transactions fees. Bitcoin can be exchanged for fiat or other cryptocurrencies, products and services. Over 100,000 merchants and vendors accepts bitcoin as a payment.

In 2018 Coinbase launched their independant mobile wallet for iOS and Android. The wallet stores the private keys on the user’s device and only they have access to the funds. This brings Coinbase full circle as it started out as a wallet, transitioned to an exchange only (claiming that they are not a wallet) and now they are offering wallet services again.

If you have the required hardware, you can mine bitcoin even if you are not a miner. There are different ways one can mine bitcoin such as cloud mining, mining pool, etc. For cloud mining, all you need to do is to connect to the datacenter and start mining. The good thing about this is that you can mine from anywhere and you don’t need a physical hardware to mine.

Coinbase is a all around awesome platform to quickly and swiftly get into the world of crypto assets. Trusted them from day one and so far so good ! The only negative situation I have encountered has been 1 . I bought $25 dollars of bitcoin and was charged twice but only got $25 worth of bitcoin .... contacted coinbase and that very same day got a email back from them saying they knew about the situation and that they where on top of it because it happened to more people that week... a day or two pass and I received another email saying my problem was resolved..... it wasn’t and still hasn’t been resolved! Thank God I only bought $25 and not a lot more ! It’s $25 I’m not going to be after anyone for that little amount of money but it definitely impacted my good experience with coinbase and their over all standing with me , my friends and my family after this situation that has still not been resolved .

cryptocurrency在线


如果目的IP地址显示不是同一网段的,那么A要实现和B的通讯,在流缓存条目中没有对应MAC地址条目,就将第一个正常数据包发送向一个缺省网关,这个缺省网关一般在操作系统中已经设好,这个缺省网关的IP对应第三层路由模块,所以对于不是同一子网的数据,最先在MAC表中放的是缺省网关的MAC地址(由源主机A完成);然后就由三层模块接收到此数据包,查询路由表以确定到达B的路由,将构造一个新的帧头,其中以缺省网关的MAC地址为源MAC地址,以主机B的MAC地址为目的MAC地址。通过一定的识别触发机制,确立主机A与B的MAC地址及转发端口的对应关系,并记录进流缓存条目表,以后的A到B的数据(三层交换机要确认是由A到B而不是到C的数据,还要读取帧中的IP地址。),就直接交由二层交换模块完成。这就通常所说的一次路由多次转发。 [3] 

我如何能赢得比特币


I have not been using Coinbase long but I have used it long enough to feel like I’m getting burned. I am using Coinbase as, what I call, a pass through as in the end, I am purchasing crypto that is not supported by Coinbase with the BTC I purchase through Coinbase. While the app itself is great as it is easy to navigate the process of withdrawing funds is not so great. I purchased BTC with the intent of withdrawing to purchase another crypto. A week and several emails later my BTC has not yet been released for withdraw. Prior to this transaction I had done several others successfully with no issues, now, for no reason whatsoever my funds are pended for “further research”. I am a patient person but as I’m sitting here waiting the BTC value is falling and the cost of the crypto I am looking to purchase is rising which means at this point I have missed out on a few hundred dollars of profit all because Coinbase won’t release my funds. I am giving only 1 star because (1) communication with Customer Service has not been great as I am still sitting here clueless on what’s going on and (2) I’ve missed out on significant profit and have no idea why or have any sense of comfort that this won’t be an ongoing issue
