随着区块链越来越火红，投资者需要懂的也越来越多。每周都有数百个新的投资项目涌现，很难去芜存菁。当项目方为了募集资金而发行加密货币Token时，问题又更加复杂了。

投资前应该如何保护自己呢？除了研究，还是研究。研究项目团队试图介入的产业，并仔细阅读项目白皮书。比起团队的理念，更重要的是实际的执行能力。但如果团队只有好的理念，尚未看得出执行力，也不代表该项目会失败。

永远要记得，只要有人赚钱，就会有人赔钱，没有人可以预测成功的项目。在投入自己辛苦赚来的钱之前，我们必须先厘清一些问题。本文带您来看，如何专业判断一个项目是否有投资的价值：

区块链是否有具价值的Token？

矿工或是验证人员可以说是每个区块链的命脉，他们藉由编写交易讯息来掌握节点。并借此获得Token作为奖励。就像请一位会计师帮您工作，是要收费的。矿工也是如此。

如果您正在研究的项目没有具价值的Token，那么为什么矿工会想投入时间和算力来保持区块链的节点顺利运行呢？而且有谁会愿意投入呢？

如果获得Token的唯一方式是透过交易和空投，那么是谁在控制节点呢？没有了验证过程，这个项目技术最终可能会宣告失败。

数据要如何进入区块链？

如果项目方尝试进入一个使用旧系统（Legacy system）的产业，企业要如何将数据转移到区块链中？不同的区块链有不同的区块大小，因此需要考虑每个区块中适合的数据量、其中储存的相关数据以及如何将数据转移至区块链中。在转移时，是将所有的数据都储存，还是只储存旧系统相关的连结和路径？

是否需要整个产业皆同意使用？

一个项目在进入一个产业时，需要考虑该产业中所有需要采用区块链技术和标准的公司。

例如，某些项目进入供应链产业。但在供应链中，要有许多公司一起采用区块链技术才能产生作用，例如供应商、制造商、运输商、零售商等等。

进入已建立的产业需要时间。问题是时间需要多久，以及在区块链的应用达成前，有多少人支持区块链技术。

如何分析和使用数据？

当数据已经储存在区块链上了，那么如何使用数据并可以为企业带来哪些好处？

如果只有将数据储存在区块链上并不会为企业或产业带来很大的价值。因此，企业或产业应该好好利用区块链的特性，以获得更大的价值。

假设美国的每个国家机场都采用特定的区块链来储存数据。就可以分析每个机场的访客总数，以及他们在做什么，每个地点花费的时间等等。这种事在以前是不可能实现的，而现在则有了区块链可以达成。

区块链技术是否跟得上业务发展

区块链的核心是「交易网路」。每秒交易量（TPS）对于区块链的长期使用非常重要，无论是对于企业或消费者。

不同的区块链有不同的应用领域。例如某些区块链相较于处理交易，更适合金融交易。

如果网路验证数据的数度太慢，企业就无法使用它，不论他有多少的优点都一样。例如，前阵子的以太猫热潮。当很多人玩以太猫时，网路便开始堵塞，而以太坊的交易时间和成本也就随之急剧增加。

设想大型国际公司以及有多少人需要同时使用区块链。若网路无法处理高流量和高使用量，那么需要即时浏览数据的公司就不会使用它。

一旦在投资前能理解并厘清这些问题，不仅能辨识高价值的投资项目，还能更加的了解区块链生态。区块链的价值不在于华而不实宣传、或是经过深思熟虑的计画、抑或是大量且繁琐的项目介绍。一切还是得回归到执行和使用。

As blockchain becomes more and more popular, investors need to know more and more. With hundreds of new investments popping up every week, it can be hard to sort out the good from the bad. When the project party issues cryptocurrency tokens to raise funds, the problem becomes more complicated.

How should you protect yourself before investing? In addition to research, it is still research. Research the industry the project team is trying to enter and read the project white paper carefully. More important than the team's philosophy is the actual execution ability. But if the team only has good ideas but has not yet demonstrated the ability to execute, it does not mean that the project will fail.

Always remember that as long as someone makes money, someone will lose money, and no one can predict a successful project. Before investing your hard-earned money, we must first clarify some issues. This article will show you how to professionally judge whether a project has investment value:

Does the blockchain have valuable Tokens?

Miners or validators can be said to be the lifeblood of every blockchain. They control nodes by writing transaction messages. And get Token as a reward. Just like hiring an accountant to do work for you, there is a fee. The same goes for miners.

If the project you are working on does not have valuable tokens, then why would miners want to invest time and computing power to keep the blockchain nodes running smoothly? And who would be willing to invest?

If the only way to obtain tokens is through transactions and airdrops, then who controls the nodes? Without the validation process, the project technology may ultimately fail.

How does data enter the blockchain?

If the project party tries to enter an industry that uses a legacy system, how can the company transfer data to the blockchain? Different blockchains have different block sizes, so you need to consider the appropriate amount of data in each block, the relevant data stored in it, and how to move the data to the blockchain. When migrating, will all data be stored, or only links and paths related to the old system?

Does the entire industry need to agree to use it?

When a project enters an industry, it needs to consider all companies in the industry that need to adopt blockchain technology and standards.

For example, some projects enter the supply chain industry. But in the supply chain, many companies must adopt blockchain technology together to make a difference, such as suppliers, manufacturers, transporters, retailers, etc.

Entering an established industry takes time. The question is how long it will take and how many people will support blockchain technology before its application is achieved.

How to analyze and use data?

When data is already stored on the blockchain, how is the data used and what benefits can it bring to the enterprise?

Just storing data on the blockchain will not bring much value to the enterprise or industry. Therefore, enterprises or industries should make good use of the characteristics of blockchain to obtain greater value.

Assume that the United StatesEach national airport uses a specific blockchain to store data. You can analyze the total number of visitors at each airport, as well as what they were doing, how much time they spent at each location, and more. This kind of thing was impossible to achieve before, but now it can be achieved with blockchain.

Can blockchain technology keep up with business development?

The core of blockchain is the “transaction network”. Transactions per second (TPS) are very important for the long-term use of blockchain, whether for enterprises or consumers.

Different blockchains have different application areas. For example, some blockchains are better suited for financial transactions than for processing transactions.

If the network is too slow to verify data, companies cannot use it, no matter how many advantages it has. For example, there was the Aethercat craze a while ago. When many people play EthereumKitties, the network begins to become congested, and the transaction time and cost of Ethereum increase dramatically.

Imagine large international companies and how many people will need to use blockchain at the same time. If a network can't handle high traffic and usage, companies that need to browse data instantly won't use it.

Once you can understand and clarify these issues before investing, you will not only be able to identify high-value investment projects, but also have a better understanding of the blockchain ecosystem. The value of blockchain does not lie in flashy publicity, well-thought-out plans, or large and cumbersome project introductions. Everything still has to come back to execution and use.
