1. Others do is suitable for themselves, you also want to find suitable for you, dcpro can, operation is not difficult, interest is not high, formal.
2. The following is for reference only:
very large
in the field of blockchain and virtual currency, such cases of losses caused by the security of exchanges occur frequently, causing great economic losses to users. The security experts of Juhui ggfx also gave a hint: there are still many loopholes in the current digital currency trading platform, for example, the most common are the following six kinds:
the first kind: denial of service attack
denial of service attack is the most important attack against the digital currency trading platform at present. Through denial of service attack, the attacker makes the trading platform unable to access normally, Because users can not accurately distinguish the degree of attack, it often causes panic asset transfer, which brings some loss
the second kind: phishing
even the best technical measures at present can not make the digital currency trading platform avoid phishing attacks. Some hackers and outlaws can confuse digital currency investors by means of fake domain names or fake pages, while ordinary investors can't identify the authenticity, so it's easy to cause asset losses
the third: Hot wallet protection
many digital currency trading platforms use a single private key to protect the hot wallet. If hackers can access a single private key, they can crack the hot wallet related to the private key. For example, in the attack on yapizon of Seoul stock exchange in 2017, the attackers stole hot wallets from the trading platform twice in a year, resulting in a total loss of nearly 50% of the assets of the trading platform and eventually leading to the bankruptcy of the trading platform
Fourth: internal attack
e to the lack of perfect risk isolation measures or ineffective supervision on the authority of employees, the digital currency trading platform also has employees' self-monitoring and stealing, and some employees with operating authority of the platform use internal trust to seek ill gotten gains for themselves. For example, in 2016, the event of employees stealing bitcoin on shapeshift caused a total loss of US $230000 to the trading platform by stealing and reselling sensitive information to others
the fifth: software vulnerability
the software vulnerability of digital currency trading platform includes single sign on vulnerability, OAuth protocol vulnerability, etc. At present, all countries have laws requiring banks or other financial institutions to implement information security measures to protect customers' deposits. However, e to the fact that the blockchain field is still in its infancy, there is a lack of such specifications for encrypting digital assets. Therefore, it is not accidental that many trading platforms have a large number of loopholes in the absence of security constraints
sixth: transaction malleability
Technical supporters of blockchain often think that blockchain transactions are highly secure because they are recorded on records that are said to be unchangeable, but each transaction needs to have a corresponding signature, and the records can be temporarily forged before the final confirmation of the transaction. Mt. GOx, which once accounted for 80% of the world's total transactions, was hacked to submit code changes to the public ledger before the initial transaction was released, resulting in a loss of 473 million US dollars< br /> &# 160;

3. The difficulty of development is not high, let everyone accept that the difficulty is heaven.
4. Digital currency is a kind of currency in circulation. It doesn't need to be bought. It exists in the form of numbers, but it has the unique number of our cash notes. At that time, every digital note can be traced back to its source. Unlike the current paper money or transfer, it is easy to be laundered!

7. In the first floor of the valley mine cave on the edge of viper Valley, we can see an NPC named shigongtou. As long as we click this NPC, we can enter the mine cave where we can dig. The deeper the mine cave, the higher the risk we will encounter, but the more abundant the relative rewards will become
we can go to the mine for half an hour every day through shigongtou. Although it's only a short half hour, it's the fastest way for novice players to earn Yuanbao. Because the difficulty of each level is different, it's recommended that players of level 35 or so can go to the third floor of the mine, while those of level 35 or below can go to the second floor of the mine, As for the first floor, because the shipment is too rubbish, it is not recommended that you go to mine
after entering the mine, we will find a large number of zombies around you. The zombie level of the third level is level 40. As long as our combat power is not too low, we can solve them very easily. Then we need to find a safe place to speed up mining. Here we recommend novice players to choose the corner, where we are not easy to be found by other players, It's only 2 zombies that can be refreshed at most once around, which is very easy for us to solve.

However, in the unregulated market, there are lots of chaos. At present, at least 90% of the digital currencies are air currencies, which will become the paving stone for blockchain exploration.
with the continuous improvement of the instry, governments around the world supervise the digital currency instry led by bitcoin, Tomorrow must be bright,
{rrrrrrr}
this is the attitude of G20 countries this year, and I hope it can help you. If you want to enter the instry of currency circle, at least you should understand the most basic trading knowledge, and recommend you a wechat public number: chive dormitory,
it seems that there are some technical teaching. I hope I can help you
9. In addition to the digital currency issued by the state, the others are to cheat money. I can tell you that if you believe in it, you will believe in ghosts
