Is bitcoin contract transaction safe

1.

Similar to futures contract, it is a trading method proposed by bitstar

the leverage of bitcoin virtual contract is shown as the leverage stability of the revenue level of legal currency: if you invest US $100, the revenue you can get = US $100 * the rise and fall of bitcoin * the fixed leverage ratio

assuming that the current price is 500usd / BTC, an investor can buy a BTC at the current price, and the principal is 500usd. At this time, the investor can make 50 more BTC virtual contracts

at this time, if the price of BTC rises to US $750, or 50%, the investor's contract income is 3.3333 BTCs, which can be sold at the current price to get us $2500, and the income is five times of the principal investment

bitcoin futures provided by bitcoin exchanges are usually traded in bitcoin. Futures is opposite to spot. Spot is a commodity that can be paid and delivered at the same time. In fact, futures is not "goods", but an agreement (contract) - futures contract that promises to deliver "goods" (subject matter) at a future time

extended data:

futures contract is an agreement that the buyer agrees to receive certain assets at a specific price after a specified period of time, and the Seller agrees to deliver certain assets at a specific price after a specified period of time. The price that both parties agree to use in future trading is called futures price

the specified date on which both parties must conct transactions in the future is called settlement date or delivery date. The assets agreed to be exchanged by both parties are called "subject matter". If an investor gains a position in the market by buying a futures contract (i.e. agreeing to buy at a future date), it is called long position or long in futures

On the contrary, if the position obtained by investors is to sell the futures contract (i.e. bear the contract responsibility to sell in the future), they are short positions or short on the futures

2.

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

contract transaction is 7 * 24 hours transaction, which will be interrupted only ring the settlement or delivery period of 16:00 (UTC + 8) every Friday. In the last 10 minutes before delivery, the contract can only be closed, not opened

Transaction types are divided into two types, opening and closing. Opening and closing positions are divided into two directions: buying and selling:

buying open long (bullish) refers to buying a certain number of contracts when users are bullish and bullish on the index. Carry out "buy open more" operation, match success will increase long position

selling pingo (multi order closing) refers to the selling contract that the user makes up for when he is no longer bullish on the future index, offsets with the current buying contract and exits the market. Carry on "sell flat much" operation, match after success, will rece long position

short selling (bearish) refers to the new sale of a certain number of certain contracts when the user is short or bearish on the index. Carry out the operation of "sell short" and increase the short position after successful matching

buy close (short single close) refers to the buy contract that the user will not be bearish on the future index market and make up for, offset with the current sell contract and exit the market. Carry out "buy short" operation, after matching successfully, short position will be reced

3. Order method

limit order: the user needs to specify the price and quantity of the order. Limit order can be used for opening and closing positions

order at opposite price: if you choose to order at opposite price, you can only enter the order quantity, not the order price. The system will read the latest competitor price at the moment of receiving the entrustment (if the user buys, the competitor price is the selling price of 1); If it is a sell, then the counter price is buy 1 price). Issue a price limit order for this counter price

4. Position

the user owns the position after opening and trading, and the positions in the same direction of the same contract will be merged. In a contract account, there can only be 6 positions at most, that is, multiple positions of current week contract, short positions of current week contract, multiple positions of next week contract, short positions of next week contract, multiple positions of quarterly contract and short positions of quarterly contract

5. Order restriction

the platform will restrict the number of single user's positions in a certain period of contract and the number of single open / close positions, so as to prevent users from manipulating the market

when the number of positions or entrustments of users is too large, the platform has the right to require users to take risk control measures, including but not limited to cancellation of orders, closing positions, etc. The platform has the right to adopt measures including but not limited to limiting the total number of positions, limiting the total number of consignments, limiting the opening of positions, withdrawing orders, forcibly closing positions, etc. for risk control

3. It shouldn't be, but it's impossible for you to make money through bitcoin, because bitcoin is a kind of transaction currency used on the Internet.

4. There are risks in any game transaction. The greater the return, the greater the risk, especially in contracts
the benefits of the contract are obvious. Take 58coin exchange as an example. If one point of BTC fluctuation is 5usdt, then 190 points will be 950u, which is about 6400 RMB. If the BTC is converted into RMB, it will earn 190 points from 5310 to 5500 now. And it costs 30000 yuan to buy a bitcoin. If you make a contract, you can buy five BTCs for more than 5000 RMB. High yield, high risk, clear market, reasonable trading
in addition, contracts are not only a risk, but also a means of hedging. In a bear market, contracts play a stabilizing role, so that assets do not shrink as much as possible.

5. Contract trading is a general term for the trading of bitcoin futures contracts
in June 2013, 796 exchange took the lead in developing the bitcoin weekly delivery standard Futures - t + 0 two-way trading virtual commodity barter contract (contract trading) in the bitcoin instry
the emergence of contract trading ended the previous history that bitcoin could not be short, and opened the prelude to the development and prosperity of bitcoin derivatives market

6. In the case of bitcoin option, that is to say, you can only get the right after the goal is achieved. In the case of delivery contract, it is different. The delivery contract means that the value has been determined.

7. Usdt is a kind of digital currency anchored with us dollar. Since there is a US dollar reserve behind each usdt, the value of usdt is very stable. At the same time, the price of usdt is difficult to rise. You can take your usdt to an app called wennabao for investment. The underlying assets in the app are mortgaged by bitcoin and other digital assets, and the annual income can reach 18%. In this way, you can get more usdt, and you won't always have so many usdts in your hand.

8. How much did you lose on the bitcoin contract< In fact, you can make a steady profit by playing bitcoin contracts. I hope this strategy can help you

I use it all the time, strictly speaking, risk-free arbitrage

for example, the current price of bitcoin is US $10000

1. Suppose you use RMB 5000 to open 20 times leverage to do long

2. At the same time, open two put options to hedge in bitoffer (US $60 cost, the world's first BTC American option platform)

& #9989; First, when bitcoin rises by US $200, that is, 2%

1, 20 times leverage, the profit is 40%, that is, 2000 yuan

2. Put option loses principal, that is, 60 US dollars (420 yuan)

3. When the two are settled, the net profit of the account is 1580 yuan

- 9989; Second, when bitcoin falls by $200, that is, 2%

1. 20 times leverage, the loss is 40%, that is, 2000 yuan

2. Put option gains $400, that is, 2800 yuan

3. Net profit is 380 yuan after decting the option cost of $60; Third, when bitcoin rises by US $500, that is, 5%

1. 20 times leverage, capital doubles, and the profit is 5000 yuan

2; Fourth, when bitcoin falls by US $500, that is, 5%

1, 20 times of leverage, it hits the burst of position and loses 5000 yuan

2. Put option gains 1000 US dollars, that is 7000 yuan

3. Minus (5000 + 60 US dollars), the net profit is 1580 yuan

note: when the contract hits the burst of position, the account still achieves profit

as soon as I see the word steady income, I want to curse
the wind blows to the center of the earth
first of all, the bitbuffer is not safe. Secondly, except for the program, it cannot close the position at the same time

9. It's easy to use. The contract is a strong proct of okex.
