Bitcoin JZ
1. The nature of the two currencies is different: bitcoin is an encrypted digital currency, and Morgan is a typical MLM currency
(1) bitcoin is a consensus network, contributing to a new payment system and a fully digital currency. It is the first decentralized peer-to-peer payment network, which is controlled by its users without a central management organization or middleman (2) Morgan is a kind of typical MLM currency, they often promise high income, the information of the founding operation team is not open, and they have the background of international large companies, so they put forward a set of seemingly reasonable economic theory
extension data: the harm of
network currency: the extensive application of
1 and virtual currency is also accelerating the rampant network robbers.
(1) in December 2006, the Shenzhen Public Security Bureau announced that it had cracked the country's largest theft network virtual property case, and 11 suspect was arrested. The gang used trojan virus to illegally steal virtual property such as tens of thousands of QQ numbers and QQ coins, and sold stolen goods on the network, making a profit of more than 700000 yuan
(2) in this case, the virtual currency Q was used as the standard of conviction and sentencing, and the police's arrest of illegal elements on suspicion of theft is a special case. The reason is that Tencent has filed with the Guangdong Provincial Price Bureau, and one q is equivalent to 1 yuan
(3) online currency is used more and more widely, for example, it can be used to buy anti-virus software online, vote for super girl, and some websites even use online currency to pay the moderator
2. Outside the business system, because indivial virtual currency has become the "equivalent" of RMB, or even "online RMB", which shows the role of "network hard currency", the illegal gains of illegal gambling can be cashed into RMB, which further promotes online gambling

Add (add) instruction
Add DST, Src / / byte / word
operation: DST = DST + SRC
1, That is, DST and Src must have a general-purpose register operand.
2. Segment registers cannot be used as SRC and DST.
3. The influence flag bits are auxiliary crray flag, carry flag, overflow flag, parity flag, sign flag and zero flag, as follows:
CF is set according to whether the most significant bit has an in (out) bit: if there is an in (out) bit, CF = 1, When there is no leading (borrowing) bit, CF = 0.
of is set according to the sign and change of the operands: if the sign of two operands is the same, and the sign of the result is opposite, of = 1, otherwise it is 0.
ZF is set according to the result: ZF = 0 when it is not equal to 0, ZF = 1 when it is equal to 0
SF is set according to the highest bit of the result: the highest bit is 0, Then SF = 0.
AF is set according to whether D3 enters (borrows) to D4 when adding: AF = 1 when there is an entering (borrowing) position, AF = 0 when there is no entering (borrowing) position
PF is set according to whether the number of 1 in the result is odd or not: pf = 0 when the number of 1 is odd, When the number is even, PF = 1

suppose that one of the two numbers is in ax and the other is in BX
CMP ax, BX; CMP instruction and sub instruction affect the same flag bits (sub affects the same flag bits as add), but the result will not be saved
JZ E; After executing CMP ax and BX, ZF flag bit 1, JZ is the conditional jump instruction, and when ZF is 1, it jumps
