Do you need to sign an agreement to buy digital currency
new coins or Shanzhai coins are now issued in a variety of ways, but most of them are pit coins. One of the characteristics of coins is that at the beginning, they are often sent in large quantities or issued at a low price. When the exchange is ready to start trading, the total amount of money held by the general developers and the big dealers is already very high, and there are still a lot of large investors, As a novice, I can only judge that it's a small retail investor. At this time, if you buy leeks to be cut, the rise of the currency seems to be very good, but it's actually deceptive, because the big investors are in it, the circulation is very small, as long as the amount of capital is small, it can rise very well. However, in fact, the external order is far less than the internal order, As long as there is internal delivery, you don't need a large quantity to get the price down. If you buy small retail investors, you will die. If you catch up blindly, there will be no turning over time
in fact, there are not many opportunities to make money, and the risk is huge
so what to do? It's actually very simple, that is, don't buy, just roll money. Now there are a lot of free money issuers. If you are free, roll money. If you are lucky, sell money when it goes up on the stock exchange, and the money will come in vain
so you want to ask? What if no one buys free money? If no one buys it, it's not worth money, it can't go up, and it can't be sold? In fact, as long as the Shanzhai coin can be listed on the stock exchange, there will be more or less, or at least some increase, because it's very simple. If the coin has a market, the market maker will have to raise the price to attract buyers, the outer market will have to buy, and the inner market will go away. The inner market has a large quantity, and it's not clean. Then it will be forced to rise for a period of time. You don't have to worry about this, You see, it's almost as good as a discount
but the principle of making money is that you should never chase up the price. You should not buy but sell. You must have a good mentality. If you can earn tens of thousands of yuan from a counterfeit variety, you should work hard at ordinary times. Making money from money in your spare time is to supplement your family, because the level of players is getting higher and higher. It will be more and more difficult to make profit from money, and you can't do serious work.
ways to purchase digital currency:
at present, digital currency is more like an investment proct. Due to the lack of a strong guarantee institution to maintain its price stability, its role as a measure of value has not yet appeared, nor can it be used as a means of payment. As an investment proct, the development of digital currency is inseparable from trading platforms, operating companies and investors
trading platforms play the role of trading agents, while some play the role of market makers. The profits of these trading platforms come from the current expenses and premium income of investors trading or holding digital currency
1. Investors need to register accounts first, and obtain digital currency accounts and US dollar or other foreign exchange accounts at the same time
2. Users can use the money in their cash account to buy and sell digital currency, just like buying and selling stocks and futures
3. The trading platform will sort the buying and selling requests according to the rules and start matching. If the requirements are met, the transaction will be completed
4. Due to the difference between the trading volume submitted by users, the trading request can be partially executed
take RBM operated by professional operation company opencoin as an example: ripple protocol was originally designed based on payment method, and its design idea was based on acquaintance relationship network and trust chain. Using ripple network for remittance or loan, the premise is that the payee and the payer must be friends or have common friends. Otherwise, the trust chain between users and other users cannot be established, and the transmission cannot be carried out
extended information:
the characteristics of digital currency are as follows:
1, low transaction cost
compared with traditional bank transfer, remittance and other methods, digital currency transaction does not need to pay fees to the third party, and its transaction cost is lower, especially compared with the cross-border payment of high handling charges to payment service providers
2, fast transaction speed
the blockchain technology used in digital currency has the characteristics of decentralization, and it does not need any centralized organization similar to the clearing center to process data, so the transaction processing speed is faster
3, high anonymity
in addition to the physical form of currency can achieve peer-to-peer transactions without intermediary participation, one of the advantages of digital currency compared with other electronic payment methods is that it supports remote peer-to-peer payment, and it does not need any trusted third party as intermediary
both sides of the transaction can complete the transaction in a completely strange situation without mutual trust, so they have higher anonymity and can protect the privacy of the traders, but at the same time, they also create convenience for cyber crime, which is easy to be used by money laundering and other criminal activities
The contract transaction of digital currency is not safe. There are still many loopholes in the digital currency trading platform, for example, the most common are the following six kinds:
1. 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
2. Phishing incident
even the best technical measures at present can not make the digital currency trading platform avoid phishing attacks. Some hackers and criminals 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
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, e to the lack of perfect risk isolation measures, or ineffective supervision on the rights of employees, some employees who have the operation rights of the platform use internal trust to seek unjust wealth 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 Fifth, the software vulnerability of digital currency trading platform includes single sign on vulnerability, OAuth protocol vulnerability and so on. 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 6. Transaction malleability the 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 forged temporarily before the final confirmation of the transaction

rules of contract transaction
1. Transaction time

Issue a price limit order for this counter price

5. Order restriction
