If you're a long-term investor, I think buying bitcoin is the best option. Because bitcoin is the best of all cryptocurrencies, holding it for long will give us even bigger gains, especially now that the price is very cheap.

初入币圈的新人首先想到的是：怎样获取比特币？在哪里获取？目前最主流的获取比特币方式主要有两种：第一种：是用真金白银去买，平台多的是这里不多做解释；第二种：就是以“挖矿”这种形式获得比特币。关注区块链行业的朋友肯定对“挖矿”这个词不会陌生。那么到底什么是“挖矿”？相信对于刚入币圈的小白来说能让你想到怀疑人生，下面咱们就简单介绍一下挖矿的概念：
 
 
 一、什么是挖矿？
 
 
挖矿不是挖煤矿，首先想挖矿就必须要有工具，挖煤你要锄头，挖矿你要有矿机，一根网线，插上线通上电就开始挖了。是通过矿机设备（你可以理解为计算机）联网计算获得数字货币。采用哈希碰撞算法，来生产比特币的过程。

什么叫做矿机：计算数字货币的设备，你可以把它当作是一台没有显示器的专用电脑。
什么是算法：不同的数字货币采用不同的算法生成，不同的矿机芯片运算不同的算法挖币
 
什么是算力：就是矿机在某个时间单位中，计算数字货币的速度快慢
什么是功耗：矿机每小时要消耗多少电
区块链领域常提到的挖矿，其实就是工作量证明（简称POW）。所谓的工作量证明，就是用来确认你做过一定量的工作。而通过对工作的结果进行认证来证明完成了相应的工作量。
工作量证明，矿工们为了争夺奖励，大家竞争去算一道题，打个比方：矿工算的题就相当于在给一个方程式求解，没有任何捷径能快速找到答案，只能是一个数一个数带进去解方程，工作量证明能说明一件事，就是你最聪明你最快，这个帐给你记，这个奖励给你。在数字货币世界里，有些非常有意思的比喻，像挖金子一样“挖”数字货币叫做“挖矿”，挖数字货币的人被称为“矿工”，而用于“挖”数字货币的电脑被称为“矿机”。
 
 
 
 二、挖矿的原理？
 
 
挖矿是通过消耗计算资源来处理交易，确保网络安全以及保持网络中每个人的信息同步的过程。
任何人均可以在专门的硬件上运行软件而成为矿工。挖矿软件通过网络监听交易广播，执行恰当的任务以处理并确认这些交易。
 
挖矿是将一段时间内数字货币系统中发生的交易进行确认，并记录在区块链上形成新区块的过程，挖矿的人叫做矿工。简单说来，挖矿就是记账的过程，矿工是记账员，区块链就是账本。怎样激励矿工来挖矿呢？数字货币系统的记账权力是去中心化的，即每个矿工都有记账的权利。成功抢到记账权的矿工，会获得系统新生的数字货币奖励。因此，挖矿就是生产数字货币的过程。中本聪最初设计比特币时规定每产生210000个区块，比特币奖励减半一次，直至比特币不能再被细分。因为比特币总量有限。
 
区块链系统能够让所有人的账本保持一致。这种让所有节点数据保持一致的机制，我们称之为共识机制。采用不同的共识算法，最终目的是确保持数据的一致性。记录工作量证明，不可篡改。
 
矿工既不能通过作弊增加自己的报酬，也不能处理那些破坏网络的欺诈交易，因为所有的节点都会拒绝含有违反协议规则的无效数据区块。因此，即使不是所有矿工都可以信任，区块链网络仍然是安全的。
 
矿工有两种：独立矿工和属于矿池的矿工。
独立矿工就是直接与数字货币网络连接的挖矿节点，而另一类矿工不是直接与数字货币网络相连，是一群矿工连着矿池，由矿池连接着数字货币网络。
 
 
 
三、挖矿的方法
 
最初的时候，我们用电脑CPU就可以挖到比特币，比特币的创始人中本聪就是用他自己的电脑CPU挖出了世界上第一个创世区块。然而，CPU挖矿的时代早已过去，现在的比特币挖矿是ASIC挖矿和大规模集群挖矿的时代。
 
比特币挖矿总共经历了下五个时代：
CPU挖矿→GPU挖矿→FPGA挖矿→ASIC挖矿→大规模集群挖矿
挖矿芯片更新换代的同时，带来的挖矿速度的变化。挖矿速度，专业的说法叫算力，就是挖比特币的能力，算力越高，挖得比特币越多，回报越高。然而挖矿的方式也经历了从一两台矿机挖矿到小矿机作坊，再到如今走入了大规模矿场挖矿的时代。
 
除了上面的装备，你还需要一个必备的工具——矿池。矿池的作用是集合大量矿机算力，增大你得到比特币的几率，同时将你未来能得到的比特币收益提前平均分配到你的账户里。
 
 
 挖矿的优势:1.风险小：挖掘币的风险远远小于炒币的风险，炒币的成本一直在变动，2.收益大：只要能够将成本控制好并形成规模，利润是十分可观的；3.不操心：只要设定好挖矿程序、做好日常维护保障矿机运行，可以实时查看收益的情况
挖矿的劣势:1.门槛高：前期投入成本较大，矿机也好厂房也罢，都是一笔不小的支出，另外还要计算时间的成本；2.收益衰减：面对这样的情况，矿主要么加大投入提升算力，要么就接受现实收益衰减的现实。

搬砖的意思什么是搬砖？搬砖的意思是工人把砖头从一个地方搬到另一个地方，而在数字货币中，“搬砖”搬的不是砖头，而是数字货币，并且是在不同交易所产生价差情况下所进行的买卖交易和转币的过程，从而达到套利的目的，因此被戏称为“搬砖”。

搬砖的风险

同一个币种，在不同的交易平台之间存在一定的差价，搬砖就是利用这个差价来套利的。搬砖套利的原理是从价格低的平台买币，然后再到价格高的平台卖出，赚取其中的差价。虽然看起来简单，但也存在着风险：
1、选择平台：交易平台的稳定性很重要，平台要选择大的交易平台，不易跑路，要有一定的成交量才行。必须支持同一币种的交易平台，必须支持能够相互转币的交易平台。
2、转币时间：平台提币存币的时间过长，容易错过最佳的买卖时机。
3、价格波动：当价格波动太大时，交易还未完成价差没了。
4、网络拥堵：造成的影响和平台存提币时间过长的结果是一样的，只不过这次不是平台的问题，而是主链的问题，在等待的时间里很可能就会错过预想的行情。

怎样降低风险

1、可以在两个平台分别放入财产，同时进行搬砖套利，避免转币时间和币价波动而产生的风险。
2、一但有了差价，两边的平台同时操作，减少了等待时间，也减少了转币的时间和价格波动带来的风险。
3、建议在两边的平台都存入BTC或ETH等主流计价币种，一旦发现有差价时，可以马上同时进行买卖操作。

总结：

搬砖也是一种合理的市场行为，它的主要目的是平衡市场的供需关系，同时搬砖也会带来其他一些有趣的市场现象，有兴趣的朋友可以多多研究，在这里就不多啰嗦了，搬砖是一种投资行为，入场的朋友一定要多多谨慎。

More and more people are realizing how powerful data is and need to be protected. Data is the new oil, and companies like FB and amazon are the new petrodollar oil champions in the world. Fortunately, blockchain provides a reliable way to break these islands of data and create a world in which data can be liberated by sharing data while still maintaining the same ledger or its original ownership, allowing creators to be rewarded.

If you really want to understand blockchain technology and invest in new projects, you definitely need to read the data security laws. I've seen so many Dapps that offer opportunities to free people, free data or create open markets. Cool, but the white paper doesn't say how to store these extremely private, sensitive data controlled by a highly developed set of international data security laws, does it? Data privacy on the blockchain is integrated with the underlying chain, or built in the top layer, which will create a huge market that is critical to expanding consumer-grade applications.

I think an ICO is still worth investing in, but it's not the golden age of an ICO anymore and we have to look for real potential projects, not all kinds of hoaxes.

I'm sorry to say that the golden age for ordinary people entering the ICO is over. This value will shift more to venture capital funds for the simple reason that many large vc funds offer significant upside. Neither propaganda nor their support networks, and most of the projects are mindless. Most vc funds are usually 100 percent.

When investing in early-stage tech companies, don't assume that the average venture capital firm knows what they're doing. They generally have no rules and no clear direction for success. The vast majority of venture capital investments do not have the desired effect. The same goes for crypto project investments.


I think most ICO and early blockchain investors don't know what they're doing, which is why they want to put their money into projects with popular sentiment because it's the only reliable mode of exploration. It's important to know that many VCS also can't accurately measure a project's success. It's hard work, and the unpredictable nature of blockchain technology and creativity makes it even harder.

Most people are reluctant to hold the public key, and even if they try to do it, some experts will still mess it up. Storing your own private key is as terrifying as hell. It's important to remember that most people don't even have the responsibility to manage money, let alone carry a secret number with them so that anyone can steal your money in a second. In the future, KMS will be a huge market. Some KMS solutions may even become like crypto-banks.

Huge amounts of money have yet to come in. I'm talking about pension funds, teacher retirement funds and large index funds. They're not in the realm of cryptography right now, but they're just around the corner. There are two reasons. First, there is a lack of hosting services to help them provide/buy/store passwords. Second, it's too unstable for them. That has turned most of the big money going into crypto into technology-focused venture funds and some family offices.

I agree with you that cryptocurrencies will never take over the world, Banks will always exist, Banks are traditional financial institutions, and we cannot forget that Banks are commercial entities. The blockchain technology will co-exist with Banks in the future.

I'm used to checking the price of bitcoin every day, which has become a part of my life. I don't think there's any good way to change that, because I'm addicted to investing in bitcoin.

The bounty hunters don't need to put in any money, but the bounty hunters do a lot of hard work to get a reward. Sometimes we spend months getting worthless tokens, and the project side doesn't pay us because their project failed.

I think China is one of the most influential countries in the bitcoin economy, and most investors and traders come from China. Even if cryptocurrency trading is banned in China, I believe the market will recover.

Any rise in the bitcoin market will be followed by a fall, and all the growth will only cause the bubble to burst. So the decline in the market is protecting the crypto market. But bitcoin is still very bullish in the long run.

I think the volatility in the crypto market is normal, we can't predict their prices, but I think eth has stopped going down now, the market is holding up, maybe it will go up again in a few months, we don't need to panic.

Bitcoin is high volatility in the market, and only then will it attract more investors. They want to take advantage of volatility for short-term profits, and volatility makes prices move so quickly that they can make you profitable in the short term.

I don't think bitcoin will be regulated by any government, and it's impossible to directly try to manage bitcoin because of its decentralized nature. Governments can regulate cryptocurrencies, allowing their people to use bitcoin legally.

Participation bounty focuses on the project itself rather than the amount. If the bounty you join is potential and successful, you will get more rewards, but most of the projects now are more like scams.

I think the market went down because there was so much counterfeit money, so many fraudulent ICO projects that scared investors. So the price of the whole crypto market has been affected, especially the price of eth has gone down a lot.
