What information does bitcoin transaction include
bitcoin, which was first proposed by Nakamoto in 2009. According to Nakamoto's ideas, open source software is designed and released, and P2P network is built on it. Bitcoin is a kind of P2P digital currency. Point to point transmission means a decentralized payment system
unlike most currencies, bitcoin does not rely on specific currency institutions. It is generated by a large number of calculations based on specific algorithms. Bitcoin economy uses a distributed database composed of many nodes in the whole P2P network to confirm and record all transactions, and uses cryptography design to ensure the security of all aspects of currency circulation. The decentralized nature and algorithm of P2P can ensure that it is impossible to artificially manipulate the value of bitcoin through mass proction. The design based on cryptography can make bitcoin only be transferred or paid by the real owner. This also ensures the anonymity of money ownership and circulation transactions. The biggest difference between bitcoin and other virtual currencies is that the total amount of bitcoin is very limited and it has a strong scarcity. The monetary system used to have no more than 10.5 million in four years, after which the total number will be permanently limited to 21 million.

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 futuresThe well-known ones must be the heads of those major exchanges. You can download them and experience them. You can see which one is most suitable for you. The experience of each exchange is different. Only after the experience can you know who is better. Indivials use the whale exchange. The heads of major exchanges are as follows:

bitcoin (bitcoin: bitcoin):
was originally a kind of network virtual currency, which can buy real-life goods. It is characterized by decentralization, anonymity, and can only be used in the digital world. It does not belong to any country or financial institution, and is not subject to geographical restrictions. It can be exchanged anywhere in the world. Therefore, it is used as a money laundering tool by some criminals. In 2013, the U.S. government recognized the legal status of bitcoin, making the price of bitcoin soar. In China, on November 19, 2013, a bitcoin was equivalent to 6989 yuan
< UL > transaction mode:
bitcoin is e-cash similar to e-mail, and both parties need "bitcoin wallet" similar to e-mail and "bitcoin address" similar to e-mail address. Just like sending and receiving e-mail, the remitter pays bitcoin directly to the other party through a computer or smart phone according to the recipient's address. The following table lists some websites that download bitcoin wallets and addresses for free
a bitcoin address is a string of about 33 characters long, consisting of letters and numbers, always starting with 1 or 3, such as & quot& quot; Bitcoin software can generate address automatically, and it does not need to exchange information online when generating address, so it can be offline [2]. More than 2 bitcoin addresses are available. Figuratively speaking, there are about two grains of sand in the world. If there is an earth in each grain of sand, then the total number of bitcoin addresses far exceeds the number of all the sand on all these "earths"
the bitcoin address and private key appear in pairs, and their relationship is just like the bank card number and password. A bitcoin address is like a bank card number, which records how much bitcoin you have on it. You can generate bitcoin address at will to store bitcoin. When each bitcoin address is generated, a corresponding private key of the address will be generated. This private key proves that you have ownership of the bitcoin at that address. We can simply understand the bitcoin address as the bank card number, and the private key of the address as the password of the corresponding bank card number. Only when you know the bank password can you use the money on the bank card number. Therefore, please keep your address and private key when using bitcoin wallet
