Insta virtual currency

1. bitcoin is a virtual currency, the world's general cryptocurrency. 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. But it's going to close soon. Bitcoin is a decentralized and open source digital currency, which will eventually reach a fixed unit of quantity: 21 million, which will not be reached before 2140. The current rate of money proction is 25 new bitcoins per 10 minutes, and the number will slowly decline. It will be halved in 2017, and then it will be halved every four years until it reaches the upper limit. Now who are the people who get those bitcoins that are proced every 10 minutes? It's a technical process, which is essentially to solve difficult mathematical problems, and hard systematic work will be rewarded. In short, mining is a process of running a program, which helps to verify transactions on the network. Unlike other transactions, it is completed by solving difficult mathematical problems. This special process also leads to its becoming a kind of free currency. Every few minutes, a new bitcoin finds a miner, so that they can protect themselves. Now mining is becoming more and more difficult. Under the leverage of market economy principle, their prices will be higher and higher. If the utilization rate is higher and higher, the prices will be higher. Using bitcoin, you can buy goods and services, convert them into real currency at any time according to the bitcoin exchange rate at that time, and sell bitcoin to other users. If you want to join the mining team, the early hardware and power costs are inevitable, so you can try various hardware settings and calculate its mining efficiency. Risk the price fluctuation of bitcoin is its biggest risk, because the whole market value has reached 1 billion US dollars, many people are eyeing this market. Last month, the value of a bitcoin rose from $30 to a peak of $75; But in 2011, the exchange rate of US dollar to bitcoin fell from US $33 to US $2.51, and it took a long time to recover. Now its transaction value is 125 dollars, so it is very valuable. Instawallet was closed as a bitcoin hosted wallet on Thursday because of the attack, and it indicates that 90 days later, if no one else claims to have received the same URL, users under 50 bitcoins will recover 50 bitcoins. For indivials, if you pay attention to privacy, want to trade a small amount of money without government regulation, and have a wallet that can be entrusted with the custody of bitcoin, you can have a try. There is still a long way to go before it can replace the existing currency. The infrastructure under it needs to be well constructed to be generally accepted. If you want to buy one or two in the near future, it is absolutely no problem.

2. I know that. It has many functions

the content in run can be customized

Customize your run input box
in windows, Microsoft provides a new way to quickly start the program: run
to open [start] - [run], in which you can directly start some specific programs, such as: enter notepad.exe to start Notepad, enter xdict.exe to start Kingsoft, etc

what is the principle of startup? Very simple, in the registry HKEY_ LOCAL_ MACHINE\ SOFTWARE\ Microsoft\ Windows\ CurrentVersion\ Under app paths, you can see many secondary primary keys, and each secondary primary key corresponds to a content that can be entered in the run

take the primary key of acdsee.exe as an example: there are two strings on the right, which correspond to the absolute path of the program by default, and the path corresponds to the directory of the program

the customization method is very simple: create a new secondary primary key with a different name under app paths (for example: smallfrogs. Exe), and then modify the default path on the right to the program you want to start (for example: C: &# 92; Program Files\ My APP\ Smallfrogs. Exe), and then create a new string path and modify it to the directory where the program is located (for example: C: &# 92; Program Files\ My APP\

then you can enter: smallfrogs.exe to start C: &# 92; Program Files\ My APP\ Smallfrogs. Exe

attention! The system identifies the program by the name of the secondary primary key. Even if you use sssss.exe to create the secondary primary key instead of smallfrogs.exe, if the content of any path is the same as the above example, the program started by inputting sssss.exe is still C: &# 92; Program Files\ My APP\ Smallfrogs. Exe
